The weirdest was that I lived in the same area as someone I met online, after he moved, LOL. I think I must have bumped into him several times, but I couldn't know he would be an Internet friend later on.
A family member and an Internet friend live in the same town. So I've met that Internet friend maybe 5 times.
Another Internet friend moved across the world to end up in the city near mine without me knowing it first. Weird. Met her 3-4 times.
Met someone online who needed a place, that person now lives as one of my friends' roommate. She has been here to visit once. I showed here this place and she signed up. But it is kind of cheating, would have been cooler if we had met here first.
