Friend will only be fellow purebloods for Alice. She will keep those most important to her in an inner circle that she will spend most of her time with. However she will stray from them to other friends in the lower levels of the pureblood Hierarcy. Of course she will have some party buddies and some people that she just keeps around for her own amusement. Friends are a good thing to have and Alice will only keep the right sort of friends. However Alice will have a fair amount of Enemies because of her spoiled nature. People will probably just assume that she is a bitch and either call her on it or just ignore her. There are probably a few people at Hogwarts that she has screwed over by "accidentally" letting some rumor or gossip slip about them. She is not below ruining someone to put herself into a better position. Like all purebloods her parents are trying to arranged a marriage to bring themselves up higher in the world but for Love Alice is really just open to anything. As a girl who loves attention she will love to flirt and have people flirt back with her but it will take the right sort of words to get her to fall into bed with another. He would need to be strong and charming and interested in Alice to get her to go with him.
