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.
Family-Unfriendly Aesop: Episode 32, regarding Pui: So, your friend abandons you because he thinks you aren't cool enough anymore? Is he unjustly judging you because of something superficial? No, this is obviously all your fault. You should therefore do everything in your power to make your shame go away and pray that he is able to forgive you. And if he does, don't even bother bringing up his questionable values afterwards. After all, you're just an awkward man.
Jerk with a Heart of Gold: Birdy comes across to some as this. He can be rather mean at times, but has moments that show he has a nice side to him as well.
