My Snap is in permanent ghost mode unless I'm actively walking to meet up with my friends downtown or something. Once we make contact, it goes back. I have people on Snap that I don't really want knowing when I leave work, when I hit the gym, etc. Not even because I think they're dangerous at all, I just don't want to be bothered as soon as they think I'm free.
I'm going to ask the guys I know who are in the same hookup culture if going off in a stranger's car is normal for them. For me -- I live alone. I have a protective pit bull and a concealed small arsenal. I'd rather invite someone here, in an environment where I know the escape routes, know the potential weapons, know my neighbors, etc, than put myself into the unknown. But I'm the size of an 8th grader and female.
