These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: My Little Pony: Friendship Is Magic S1 E11 "Winter Wrap Up"
Accidental Aesop: The main focus seems to be on Twilight realising everyone has a talent and unique place. However, we also learn that within all of Twilight's angst of her screwing up the ceremony, every single other pony has been doing just as bad as her, and the supposedly blissful Winter Wrap Up has been a disorganized mess before she even came. As such a second Aesop could be "Everyone makes mistakes, so don't feel singled out because you made one".
AccidentalBroken Aesop: Although the real lesson of the episode is "Everyone has a talent to contribute to a group effort," since Twilight's skill is organization, and she happens to be a member of the aristocracy, it can read as "The peasantry cannot organize themselves and therefore need the nobility to drive them in the right direction."
Alternatively: Managers and organizers are the ones who were Kicked Upstairs because they can't do any of the real work.
Why was Twilight having such a tough time getting her saddle on in the Cold Open? She'd probably been using her magic to help her do stuff like that for years, and this was the first time she'd tried doing it without.
"She's awful strong for such a little pony"...and a unicorn mare. All the other ponies pushing the snow plows are Earth pony stallions. Word of God states that, according to the magical rules of Equestria, Earth ponies have greater physical strength than unicorns or pegasi, and stallions are typically bigger and stronger than mares. Applejack has every reason to wonder at Twilight's ability to even move a snow plow, let alone move it faster than the stallions.
Ear Worm: Say it with us! Winter Wrap Up! Winter Wrap Up!
It later turns out not even Discord can resist it.
Harsher in Hindsight: It's possible the actual reason AJ was so furious with Twilight was not so much because Twilight made a huge mess, nor exactly because Twilight used magic, but because the Earth ponies who founded Ponyville were her ancestors. Including Granny Smith who AJ clearly adores. Twilight's use of magic was not just disrespectful to tradition and to Earth ponies (who don't get near as much love as pegasi and unicorns do (from fans) due to their natural powers being more Mundane Made AwesomeSuper StrengthGreen Thumb abilities than Inexplicably AwesomeColor Coded Magic or Flight), but to the Apple family, particularly Granny Smith, and by extension, AJ herself, too.
