Bad Moods

Vanessa is off school for "UEA" and now she is bored and gets mad at her family for not letting her do things. She has been in a bad mood for 3 days and doesn't care about anything, she thinks that she can get away with anything, and then when we do let her get her way we don't hear a "Thank You" and then her mood doesn't change. so then she puts me in a bad mood and I don't like being around her when she is so upset. she gives you the silent treatment or if you ask her a question her answer is "I don't Know" and she says it so mean that you just want to slap her. I love her but sometimes she makes it so hard to love when she is so disrespectful to her family, but her friends she worships the ground they walk on.
