lint opener fickle style.....

PUA*picks fair sized lint off girl, gives her odd look*
PUA-wow i just saved your life, you could have looked like a fool.
HB-haha thanks blah blah.
PUA-and your friends didnt even tell you about it :O:O *playfully* (if she has any with her).
HB- haha yeah whats up with that guys?!?----to her friends blah blah.
PUA- *looking at the lint for a while* wait a minute?!, did you put it on you on purpose?!
HB- what? what are you talking about blah blah.
PUA-i think you put that on before you go out....to get guys like me to come and talk to you?! wow your a clever one i think im gonna try that one next time im out!
