This afternoon I went into my bedroom and heard a noise in the ensuite. When I went in I could see the window cleaner was cleaning the window with the pole/brush/water system he uses. I looked out of the bedroom window and thought it was odd that I couldn't see his van or his hose on the drive.
I went downstairs 5 minutes later and there was no sign of him (in the garden or street), no other windows cleaned and DH said he hadn't seen him. We're having work done on the house so the windows are filthy and the house is encased in scaffolding so it wouldn't be very easy to reach one small upstairs window unless you were on the drive standing directly underneath the window.
If I hadn't sent DH upstairs to check, I'd think I was going mad but he confirmed that the window was wet and clean. There's no way anyone could have accessed the side of the house other than from the drive but there was no one there so what the hell happened? If I have a phantom window cleaner I really wish he'd cleaned the lounge window as it's covered in seagull crap!
