Whodunnit!

I was lucky enough to see this young male on my way back from walking the dogs. To paraphrase Stevie Wonder “Isn’t He Lovely!”
My wife is on her way down to Edinburgh to stay with our daughter for a few days. She made a sandwich to take with her on the bus, wrapped it in foil and laid it down beside her case to get something else. When she came back a couple of minutes later, there was only the foil left, and it wasn’t me or Joe!
When will we ever learn!!!
