VioletSky, I think your suggestion of “Where do you live?” is a very sensible one and could avoid problems in a lot of situations, and in real life as well as online. It might be an easier way to find out a person’s background if you are interested but don’t want them to feel that you don’t think they belong - if that makes sense! Thank you.
