I been lurking this sub for quite some time although im still trying to pickup on particular things... like the following; How would one, whos plugged into TRP deal with these situations?

A girl talking to me, venting the problems shes going through with her BF (emotion tampon dealing)?

Approaching a girl without lowering your SMV; I agree that as a guy in this feminist society, we have to be the ones to put in the effort just because we have to, but in doing so i feel like im putting my reputation and image on the line just for a piece of ass ; Do i have to approach a girl to initiate a conversation or are there methods of making her talk? Besides the good ol' eye contact.

If you know a girl is using you only when she needs you for support or something along those lines...? (face to face - Over messages i simply dont reply)

and finally, dealing with those bitchy girls that are always serious or even argue with you, for example I had a girl in my university sitting a few tables away from me death staring me and saying "Jesus christ" really loud because i told her to 'shhhh' as a joke... I usually laugh or reply with something witty but sometimes my head is just not in the game. TRP method?
