Honestly, I don't know what I'd do if I saw that.
If I was with Dh or some other people, I'd like to think that I'd step in and tell them I'm going to call the police.
Alone, I wouldn't want to risk getting punched myself by the male or female.
Very interesting and it has certainly got me thinking.
I have intervened with a group of young women who were pushing another teenager around. After that experience (only verbal but it still was horrible), I thought I'd butt out in future.
