I'm really freaked out! I live in australia so it's half past midnight and just as I was dropping off to sleep our doorbell rang. Dh is still at work and i thought it was him having forgot his key so went down and looked through the spy hole and nothing was there. Checked the door was locked and it is. It's really scared me. Can doorbells just ring on their own? Its an electric one that does ding dong, not a brrrrrring bell one - can you tell I'm not a doorbell expert?!
While i was away a few weeks ago dh said this happened once at night and no one was there.
So either a dodgy doorbell or someone's messing with us. Aaaaargh.
