It tends to come up if I'm drinking

It's sort-of a go-to ice breaker at university, along with all the usuals:
- What are you studying
- Whereabouts do you live
- Aren't the buses crap
- What year are you in
But yeah, there's always a bit of a side-comment somewhere along the parties or nights out where the person you've just met is like "so are you...?"
I don't bring it up though
