Spoilers if you havent seen the episode "Party for one" of My Little Pony; Friendship is Magic
I LOVED this episode, even though I thought the ending was a little bit sugary and sweet for me. I mean; Yes, they wanted it to be a surprise for her, therefore they avoided her and lied to her. But I still think Pinkie forgave them too easily for shutting her out like that.
I've been in Pinkies (horse)shoes several times during my childhood; Problem was that the people really DID wanted to avoid and get rid of me. I've lost the count of times people I thought could be my friends abandoned me at games like hide&seek, wich resultet in me hiding in an uncomfortable place for over half an hour, and when I got tired and started looking for the others, they had gone in to one of the friends to play video games 10 minutes after I had hidden. Or the time some classmates told me to wait by a bridge outside my house for when we were gonna go fishing; The deliberatly biked around that area just so I wouldn't see them.
And I know most logical people now think "But why did you still try to be friends with them?" Answer; Because having a friend during a brief time, even though they're cruel to you, abandon you at random and tell you you're ugly or stupid just because you're a girl (hang out mostly with boys) was still better than always being by you own, at least it felt like that. (Hey signs of an unhealthy relationships when you're an adult!)
Which makes me think that Pinkie has some serious issues when it comes to people, in some kind of way. Some are discussing on youtube that she's adopted (Which make sense; Look at the colours of her family!) and therefore feel abadoned by her real family. Otherwise, I can imagine her having the same issue I have, which is to trust that people really like you, adn that they won't just grow tired of you someday, specially since she seems to be the odd one wherever she is. That might have been a bad thing for her when she grew up. The reasonable part of your brain tells you that's silly, but years of getting those thoughts confirmed trough other people treating you that way makes your guard stay alert.
Long way of saying that I think the gang owed Pinkie a proper apology in the end of the episode, not just "Oh you silly filly, you should always trust that we want to do what's best for you." That kind of thinking broke my heart way too often
(How hard could it be that one of the gang could be with Pinkie and distract her? I know not plotwise, but she could have yelled at them and suggested that)
What more to say? Gummie's cool, Rainbow Dash and Fluttershy's excuses were hilarious ("He's a bear" xD), Spike takes things way to literal ("A pegasus who's afraid of heights? What's up with that?) and after reading Cupcakes (People honestly getting nightmares of that one?), I can understand what's so funny with RD getting Pinkie out of the house xD

Someone at Equestria daily explained it a thousand times better than me;
That was weirdly distressing for an adorable show about ponies aimed at little girls.
- I thought the moral was sort of weird. "Trust your friends" is fine as a moral in a general sense, but uh... Well, I'll come back to this.
- Trust is a really big issue for Pinkie Pie, apparently, since a lot of episodes heavily involving her come back to this. It pretty much WAS the moral of Feeling Pinkie Keen, as well as the whole "breaking someone's trust is the fastest way to lose a friend FOREVER" thing.
- Pinkie DOES trust her friends. Keep in mind that they're the ones that started lying to her. Also keep in mind that she actually believes their lies at first, or at the least is willing to give them the benefit of the doubt.
- So what I think initially sets her off is that her friends are lying to her. The abandonment issues come up as a result of this.
- That's why the moral is kind of messed up. Pinkie Pie DOES trust her friends, and only stops trusting them after they give her a reason not to.
- Soooo... the other five ponies sort of went against the elements, by lying and being disloyal to Pinkie by violating her trust and so on. The apparent generosity of the surprise party was... not really in Pinkie Pie's benefit so it comes off as a sort of faux-generosity. Unkindness is implicit. And then Twilight misses the point entirely, not realizing that her friend has /issues/ and ends up blaming PP's problems on a lack of trust.
- Finally, Pinkie suddenly getting better at the end was about as disconcerting as her sudden breakdown. The abruptness made it feel less getting better and more... I don't know, the remnants of a shattered ego desperately trying to pull itself back together.
Yeah, seriously, what the heck?
If it's for schoolwork, and the assignment requires pictures but not that you do the pictures yourself, go for it.
If it's any kind of PR-thing for events like cons or the like, I'm saying no.
At the same time, I like the moral of this one from Pinkie Pie's point of view. Again, having manic-depression makes it difficult to trust those close to me sometimes when my gloomy side takes over and stories like this are a reminder that not everything your friends do should be taken so seriously. The moral could have possibly been worded more appropriately, but keep in mind that they wanted to make it easy for younger audiences to understand. Not to mention I'm sure they didn't want to outright state Pinkie's mental disorder. It's pretty obvious that she (and a few other characters in the show) have some deeper issues, but they're downplayed solely to provide a little bit of realism to them and give a bit of amusement to older viewers. All things considered, a psychological disorder that makes it impossible for you to control when you're sad or happy is kind of an uncomfortable subject matter for children, don't you think?
I really hated that school and then i had ONE friend who felt the same way. But she moved away in fourth grade. I was alone EVERY single day. and when we were waiting for our teacher i usually sat alone in a corner while everyone was chatting, and talking about me. And even when i got hurt they didnt even care! only when an adult was there they went to me and faked being "nice" to not get in trouble, i just hope itl get better over the years. wow sorry for the SUPER long comment
