Heh.... I've warned my daughter to expect that sort of thing from me if she ever brings some unworthy fella home.
When I was fifteen I scared off one of my (divorced) mom's wanna-be boyfriends in similar fashion. I'd watched the guy for a while, and had concluded that he was a no good, conniving con artist.
One evening when my mom was out of earshot, I flat out told him that I didn't think my mom was right for him, and that I was a troubled teenager who liked to play with guns.
Never saw hide nor hair of him again.
Laugh hysterically for no apparent reason, and the world tends to keep their distance.
I'm a believer in counterintelpro.
Especially where my daughters were concerned.
