Years ago, a young man honked his horn for my daughter to come out for a date.
Instead, he got me.
I walked out to the car, opened the passenger door and sat down. I said "here is how it works, you ring my door bell, I let you in. I ask where you are going, and what time you will be bringing my daughter home. IF I APPROVE your plans, she can go out on her date with you. By the way, I am a reasonable man. If there is a good reason to stay beyond her curfew, we can talk about it."
I only had to do that once. Word got around, and the boys knew that blowing the horn was not acceptable.

This particular daughter is now well out of school and works over in a different town now and these guys are at her work. They seem to be getting the message now.
I love that. My oldest girl is turning 12 this week, so I have a few more years until the dating starts, but I'm going to have to remember your method.
