a responsible “adult” would not buy a ton of horses knowing they are going out of town in less than a month for a while and then frantically try to sell them 10 days prior just so her parents won’t have to feed a bunch of horses while she’s gone. How about- actually hire someone to feed and care for them while you are gone, or perhaps grow the fuck up and think about your actions before jumping into shit.
Peter has next to no acting skills, and he knows it, so he comes to a point where even in his civvies, he doesn't try to act surprised. Doesn't bother. Not at all. Like, a villain comes to the school and immediately runs up to him and threatens him, and Peter gives them this deadpan look and starts sassing at them, and Harry and MJ are just in the back like "Peter whAT ARE YOU DOING?!" Puny Parkers becomes Balls of Steel Parker around the school. But he's just. So tired. He doesn't care anymore.
