I duno, maybe guys should..but, #1, 95% of girls don't approach guys anyway, it's usually our job, #2, wouldn't it be cool to be walking through a public place, and, just outa NOWHERE a(hopefully goodlooking) guy comes up to you?..it'd be all flattering & stuff..now, the guy would of course have to give some sort of signal that he was a witness once the convo was initiated...Like, when he comes up to you, the first thing he should say is "1914", and, you reply w/"Psalms 83:18" as a signal that u understand...
