I was burgled a few years ago while me, my wife and 4 kids were asleep upstairs. They came in and quietly disconnected every electrical item in the living room. They then moved into the dining room which has patio doors and barricaded the internal door with the sofa in case we woke up and came down. They then proceeded to remove all of the cushion covers to use as makeshift bags to carry their (i say their loosely) swag. Loaded it all up into my wife's car, and drove off. They even left an empty can of coke on the dining table that they helped themselves too from the fridge.
Took a while to recover from that. Couldn't sleep properly for months.
Add insult to injury, it took the insurance company 4 months to pay out because they thought the robbery was suspicious as we were in the house and didn't hear anything.
I remember the police officer who came around when we reported it. She hated insurance companies and coached us before we called the insurance company. She told us to say that the car keys were hidden and that the patio keys were not in the door (internally obviously). Even though she said that everyone keeps their keys in the door or near it in case of fire. She also said that if the car keys weren't easy to find, they may have gone upstairs to find them!!
From that day, we always leave our car keys out and never take them upstairs.
Scary stuff.
There's some real scum bags out there....
