We've been in our house for well over a year now, but still get loads of post for the previous owners - serious stuff, like magazines and what look as though they might be statements.
Up until recently, we've been forwarding it, but I've got to the stage where I can't be bothered. In fact, I unwrap the magazines and read them. My OH thinks I'm being mean, so I'd be interested to know what others think.
By the way, they are still alive and live not to far away.
