When I was younger I worked in Post Production in Australia. There was a CUTE girl I worked with. Smart, good-looking but I worked in graphics/creative, and she worked in sound/admin.

We flirted, but she had a BF, so we just left it easy and there were never any lines crossed.

I decided to move to the UK and expand my work horizons there. About a year and a half later I visit a dive bar in London, and I am listening to my fave band. I go to the bar to get a drink and guess who's the one serving me?! We both just stood there in awe that we could meet each other on the other side of the world like that.

I got great drinks all night, and we still never went any further with a relationship but it was just a cool experience / co-incidence for both of us.
