OK - only 1 rule - you can only post one little irritation:
My DH uses an electric toothbrush as he would a normal one - but he just whizzes it round his mouth, scrubbing as he goes [ruining the brush head] and with his mouth wide open so it spatters toothpaste all over the mirror and the shower screen next to the sink. And for nowhere near the 2 minutes the timer is set for. No wonder his teeth are cr&p.
