We moved into our new house in January 2015. The family who lived here before seemed lovely and really thoughtful about everything except for their post. They left some pre printed stickies with their new address on but didn't arrange a post redirection. We ran out of stickies after a few months last year but yet the post still comes. I redirect a handful of letters, most of it official looking not junk, every few weeks. But I'm getting bored of sorting it out.
Would I be unreasonable to return it to sender now? Or do I keep sending it on? WWYD?
