Strange thing I've noticed: a significant number of girls I meet in Colombia ask if I have a gf. This was never the case in other countries - girls assume that if I had a gf I wouldn't be talking with them in the first place. Interestingly, at this time I actually am in an open relationship. I haven't had a chance to ask one of these girls where they're coming from with this question - curious if folks know why Colombian girls keep asking and how they view a yes vs no answer.
