As a father of a teen daughter, I can just imagine. But being a large man, I think would have to warn the kid of two things. Move, and at best you just get an ass whooping.
But I am sure that having an intruder in your home, who your daughter says she does not know, would make a man go through a thousand emotions in ten seconds.
That is why they make cars.
