I can't be seen in public with you." If someone tells you that they can't be seen with you in public, that's a good sign that it's time to drop them

My friend sister hooked up with a classmate a few times and says they got along very well, sometimes coming over to hook up and never getting the chance because they would get so lost in conversation. So one day she asks him, 'Hey we get along well and I think you're pretty attractive, maybe we can go on date?' Without a beat the guy looks to her and says, 'Listen, I'll have sex with you, but I can't be seen in public with you.'"
