When hubby and I first started going out together he got a job as a security officer for a while at a very old disused hospital down in Cornwall (UK) he used to do 12 hour shifts there..sometimes through the night. He would be the only person on the site..he hated it as it was very creepy and lonely.. so sometimes I would break the rules and go with him and spend the night there!
..we would sit in the office and listen to the radio through the night pigging out on snacks and talking. He had to do hourly patrols of the site and an hourly check call to headquarters to report that all was fine on site...the nearest toilet to the office was a little way down a corridor...I went to the Loo this one time and was sat doing my thing..like you do...
when the old fashioned doorknob started to turn and the door shook..I thought it was my hubby mucking about so shouted out for him to 'go away'
...I went back to the office and he was on the phone doing his hourly check call to headquarters and gesturing to me to keep quiet!..when he got off the phone he asked me why I had been shouting out and that it wasn't good timing as I obviously wasn't supposed to be there....so who the Heck was trying that door I wonder???
still creeps me out thinking about it...after that hubby and I went to the Loo TOGETHER!
