My biggest worry while we still live in London is not being burgled, but being burgled and them finding Lexy. I have extra locks on my front door because of this. My area is pretty good, my neighbour is home all day so we always have a some kind of presence there. That and he's a high school teacher and any "kids" avoid the house like the plague. Still worries me silly. Possessions can be replaced, over time the invasion of privacy you feel will disappear, but you can never replace your babies.
