Just watching Location, Location, Location and wondering whether anyone has ever seen a house they used to live in on there (or another property show). Like, presumably if they're looking round a house they would tell the current owners that it'll be on tv, but any past owners would get a surprise when it popped up on screen!
If you have, was it weird to see people walking round "your" house? Had it changed much since you sold it? Did they make any comments on anything you had decorated etc?
