I'm afraid I'm far too security & safety minded! Dh is a burglar alarm engineer, so I've had years of him drumming it into me! What bothers me is that you have all your lights on when you're in, like a big neon light saying 'I'm in - don't burgle me!' Then, you go out, switch everything off, in case there's a power surge or summit and the whole house goes up in flames, but the burglars have been watching, since they know all the houses are crammed with goodies, they see your lights are all off and bobs ya uncle - lets go shopping!
I'm taking it too far aren't I?
