Repression

You barely acknowledge Jessica's presence. She's one of your sister's friends anyway, which makes you even less inclined to help her. You say something about being really busy and having a lot to do on your own computer right now. As Jessica leaves, you continue to think about Mom, and that kiss.

Lunch time comes around and you sit to ponder it even more, fortunately without your idiot "friend" Aaron buzzing in your ear. You hear your sister's boyfriend Butch bragging at the next table about some chick he slept with last night, that apparently wasn't your sister. This is why your sister SHOULD listen to Mom! She knows what's best, and knows how to protect you from bad people.

Lunch ends and you attend the rest of your classes without incident. Finally after school lets out, you run into your sister. She sees you, but refuses to talk to you.
