I live with 3 girls, all of whom are off limits to me (don't want shit to get nasty if something goes wrong so won't even try to get with any of them). However, I wouldn't mind TRP'ing them and building up my value compared to them etc.

If we're in the kitchen making food or something and talking, one of the girls might talk to me about her problems. Whats a way to tell her that I don't really want to hear it (and also build desire for her to get my attention) without being rude?
