Although I like the characters of Fred and George, I've never been able to like them as much as most of the other main characters in the book - particularly Fred. Between the two of them, I like George better than Fred. The main reason is because at times, I perceive them to go beyond teasing, and I think they can be quite unfair and unkind at times. Although Percy was very pompous and full of himself, I think they gave him more of a hard time than he deserved, and they do pick on Ron quite a lot. Also, they were never really that pleasant towards Cedric, either, and since Cedric is one of my favourite characters, I've never liked the way they behaved towards him. The only thing he did wrong (in their eyes) was beat Gryffindor at Quidditch much, and it seems that that made them bear some sort of a grude against him - in GoF, when they meet him and his father, Cedric says "hi" to everybody, but Fred and George just nod at him, and it states that they "had never quite forgiven" Cedric for beating Gryffindor. There were a couple of times when they said some things about him that I thought were quite rude and cutting. Don't get me wrong, I do like the twins - I just don't like them as much as most of the other characters, and I sometimes disapprove of the way they act. I think they should treat Ron a little better, and I think they should have been nicer to Cedric, personally. From reading the books, though, it seems to me that George is the kinder of the twins. It seems to be mainly Fred who says the more hurtful things.
