My brother was old fashion when it came to those things. His daughter’s date would find him sitting at the kitchen table, oiling his shotgun. My brother would say nothing more than “have her home by 11 pm. Any questions?”
A long time ago when my daughter was a teen I had just returned from the range and was cleaning my handguns. She introduced her boyfriend. I just said “Hi” and continued cleaning. He never asked her out again. My daughter was POed at me for weeks.
I’d have her home at 11:30 PM just to make a statement.
Have you seen the one about tossing a shotgun shell to the date? Do that, then say “It moves a lot faster after 10pm.”
