Guy on train WOE IS ME!?

Just start a casual conversation right out of the blue. He's just a person, not some untouchable god. So you may find out he's married, or gay, or just not interested, at least you'll know. The worst that could happen is nothing, which is just what will happen if you do nothing. Girls are not the onlyones that are shy and nervous around the opposite , you may find that he's been trying to find a way to meet you.
