Has anyone seen my car?????

This is my eldest son, he's 17 has recently passed his driving test and against my better judgedment, I was talked into insuring my car for him to drive.
My car is a very modest affair but it cost the national budget of Chile to add him to the policy.
Now you dont have to be Hercule Poirot to guess what has now happened, my car is no longer mine, it disappears at night for who knows what-where, drugs, sex, ram-raids, but for now still is back in it's place in the morning.
To all blippers who have fresh innocent babies BEWARE!!!!, this is your future, they grow up and hit the street's, but I'll get my own back he's bound to make me a Grandad someday, and then it's sweet revenge.
