At least you were visited by a professional - someone simply wanting to take something to sell and pick up any easily available cash - not some true low life who trashed the whole place with paint, cooking oil or worse.

Sometimes you've got to take the attitude that it could have been much worse, and you actually got away with something.

Shame about the kilt money though - maybe you could get a loan to make the place more burglar proof and save a bit by doing the work yourself?
