Wood you believe it?

It's Derelict Sunday, and absolutely chucking it down. So I'm afraid what I'm posting today is a bit of a Victor Meldrew shot....

Our next door neighbours have a habit of cutting down bushes and trees to the fence, and chucking the branches into our garden (what was a gorgeous cherry tree that was here before they moved in). This time, a broken beam also was chucked over. No idea where from - it wasn't from our garden. I have to say, I'm generally very mild mannered, but am really irritated by this petty behaviour. We have never done anything like that. We are quiet - kids use headphones etc...
