Hey, tessaone. You don't say where you know this man--work, a neighbor, etc. I think the main thing is to get around him. Not pushy, but maybe strike up an innocent conversation. You might need to do this a few times to see if he responds and truly seems interested in you. If things seem to click, then maybe ask him if he would like to grab a bite of lunch or a cup of coffee or some such. (Not at night, unless he asks, because that is generally considered a date.) Then go from there.....

Anybody else have some ideas?
