It’s probably something I’ll never need to worry about but I’ve just been looking at a bit of property porn - huge houses with indoor pool, gym, cinema room. I think I’d never be able to have a relaxing swim in the basement or shut myself in the cinema room as I’d be worried about security in the rest of the house. In my house I can pretty much see all the house from the lounge and it’s easy to check front and back door are locked. I know some people have staff but not everyone in these houses would. I don’t think I’d feel confident swimming or watching a film if I was home alone.
