Get his number or MSN. Flirting through text can be a lot easier, and very fun. ^_^ Plus if anything goes too far you can just say you were messing around. But yeah I've had some fun flirting with a few people on MSN that I know IRL, and it's helped us get together in a couple of cases Though I don't know if my idea of flirting is the same as it often involves somewhat dirty conversation. xD
