I've been trying to cold approach for years but I've found it nigh impossible - instead I've found it much easier to go up to girls (or just anyone) to warm myself up first and get into the habit of talking to strangers. My favourite is asking people for the time, explaining my phone has died (this gives them a hook to make a comment if they want). The problem is I'm spending a lot of time on the train, and with clocks everywhere it's not so viable - I can't think of much else except asking for directions. I know people will say 'just strike up a conversation' but I need a sort of a plausible deniability to make it easier.

I remember seeing a program once that was like 150 days of approaches, with the first 10-20 being stuff like this. Does anyone know what I'm talking about? Otherwise, what are some good excuses just to go up to girls and ask them something or strike up a conversation - especially in the context of public transport?
