The biggest threat to your survival......

[NorthernRaider]

Assuming anything is a short cut to trouble, damn glad you are OK though, I admit that after 7 years living way out of town I too got complacent with checking doors, at least twice i have returned from the school run to find I left the door unlocked, and once I went out the front door, into the garage, then went round the side to work in the garden, thus leaving both the front door and garage door wide open for over an hour!!!, I'm slowly getting a grip.
