We came back from a walk this afternoon, took our shoes off in the hall, and when I went to put mine away, I noticed a pair of scabby Nike trainers in the shoe rack that I didn't recognise. I immediately thought they must be my son in law's as they came last weekend, having been cycling and while he usually changes his shoes in the car, he may have changed them in the house and left them behind. But they aren't his, apparently (I sent him a photo) and they don't belong to DH, they are the wrong size for my son and the only other male who has been here recently was the man who came to measure up for blinds - and I know he put his shoes back on when he went. We are flummoxed! I don't know why we have never noticed them before. Anyone lost a pair of trainers?
