I agree. A 19 year old being told to stay home by her parents does not seem weird whatsoever to me.
Maybe she didn't have access to a car before she went to Leah's and Lisa wouldn't let her drive her car. Since she returned from Leah's, Lisa says that she was a changed person...polite, sweet etc. She also had the Kia for her own transportation. I get the feeling that Lisa was not telling her where to go and what or what not to do, but was just concerned for her and wanted to have an idea of her plans. Lisa said last night that she gave JC money to buy cigs for LISA. I am sure that Lisa would prefer that JC not smoke, but I doubt that smoking was a big issue to either one of them. JMO
