Young Lily started crying, she didn't like the teachers at Hogwarts and thought most of what they were learning was a waste of time, but she had friends there.  If her mother was still alive, it would be a blessing. She could go back home and study, but what would expulsion mean with her gone? She wouldn't be allowed to be home on her own. She would probably be sent to a different school hundreds of miles away and never see her brothers again.
