Just to remind you that your actual daughters might also become lesbians (so you don't only have to worry about eventual punks)

.
Then, may I respectfully suggest that you either start giving a fair amount of money to some kind of religious institution or invest in heart medications.
Of course, Grae's solution is a valid one (in my very little opinion) but, if the punk's father has a good lawyer, you still might have to invest in heart médications.
Relax or you'll get old way before time. One last thing, quit worrying too much and care a lot (no offense). That has a tiny little chance of saving you from heart pills.
