Remember to pull the boy aside (when he shows up for the first date) and tell him nice and quietly that "She's my little girl and there's NOTHING I wouldn't do for her.
If you hurt her, I will hurt you in return.
Remember that I have a gun, and I have no problem going back to prison for my little girl!"
Then see if he sticks around....

"If you're arguing with an idiot, make sure he isn't doing the same thing."
One of the kids visiting my daughter wouldn't give me his name. Thought it was funny until I told him he had one more chance before his dead body hit the center of the street. His buddy said I told you so...
