Rule Three from "10 rules for dating my daughter" :
I am aware that it is considered fashionable for boys of your age to wear their trousers so loosely that they appear to be falling off their hips. Please don't take this as an insult, but you and all of your friends are complete idiots. Still, I want to be fair and open minded about this issue, so I propose his compromise: You may come to the door with your underwear showing and your pants ten sizes too big, and I will not object. However, in order to ensure that your clothes do not, in fact, come off during the course of your date with my daughter, I will take my electric nail gun and fasten your trousers securely in place to your waist.
