Our primary school toilets were very old-fashioned and had khaki-coloured doors. The cleaner's cupboard was next to the rows of cubicles and was the same length as each cubicle, but slightly wider, with two doors that were always locked. On my first time there, I thought it was a special, extra-big toilet with lots of exciting things inside. I figured it was always locked because someone else was in there and it was very popular. For years I believed this and was desperate to get in there, and I could never understand why someone always beat me to it. Even if I went in class time, it appeared to be taken. I couldn't believe my bad timing.
It was only about 5 years later when I was in there one day and the cleaner came in to get something out of the cupboard that I realised the truth.
