Yeah, you women can scoff, but at least I've learnt something after reading those replies; something I know will work if I find a woman crazy enough to marry me!

So basically, if I upset her for some reason and get banned from the bedroom, I just have to stick my bottom lip out and huddle my shoulders.  It's good to know it's that easy and that it works every time!  Without that knowledge I'd have been inclined to sleep on the sofa until she was asleep, then I would have just creeped back into bed all stealthy like!
