I find myself often doubting whether I should approach a girl. E.g. I am at the buss stop and there is a cute girl listening music and browsing on her phone. Also there are old people near by and if I go to speak to her they will hear 100% of the conversation. Should I just go with a fuck it attitude and risk rejection in front of other people? I am also wondering if I should only approach at places women will be more likely receptive - parks, mall, bars, clubs.
