Harry was kind of a dick to everyone
Harry definitely took teenage angst to an extreme. Not only did he talk back to literally every adult who — oh, we don’t know — acted like the adult in a situation, but he routinely snapped at his friends for trying to look out for his best interests. Then there was Pavarti Patel at the Yule Ball. And Cho Chang after Cedric died. And Dean Thomas when he was hanging out with Ginny. Oh, and that candy incident with Neville Longbottom.
