So my game pretty much is "Hey my name is Jakub, I find you cute, can I have your number?" which sometimes* I use in open space, but as I really dislike attracting attention around me, so I find it difficult to just approach girl like that in bus or elevator because I am stuck in those places and I just can't leave them whenever I please.

sometimes* - because I am pretty shy about approaching girls I don't know atm, I did it once in this month. Maybe I should focus on open space approaches so maybe I will be comfortable enough to do something in closed spaces?
