4 I guess I sort of answered that. Social situations are daunting for me. That said, the better I know the person, the easier it would be to get around that. Also, if it's something embarrassing or personal that I have to point out (case in point), it's harder because I will be causing them embarrassment, even though they'd probably want to know about it. It would be different if I saw a spider on someone's back, or something like that.
