He's 17, and just back from Reading. I'm the only one here, but under strict instructions to wake him. I can't. Have tried banging on the door, the wall ajoining the bathroom, shouting + screaming, no luck.

Can't break into the bathroom unless I break the door down.

Any (sensible) suggestions as to what I can do/how I can wake him?

Ta. This is not how I wanted to spend my Monday evening.
