I've never had problems with the family locking me out - they're all upstairs snoozing while I'm misbehaving. However one night years ago around 2am I decided to duck back unside for something or other and SLAMMED into the screen door in the dark (forgetting I'd closed it earlier
)
The next day a few people at work were puzzled about the criss-cross welt all across my forehead though - almost drew blood
The crimsafe bounced me off like a trampoline and every dog in the neighbourhood went nuts for a few minutes
Should probably count my lucky stars didn't break my nose.
