On the Tuesday that just passed, I was in the library doing my helpsheet for math exam later in the evening when I needed to go to the toilet. So I put down my pen, took my phone and walked up the stairs.I pushed open the toilet door, walked in, looked up and saw a guy in front of me. He stared at me. I gasped, turned around, hurried out and checked the sign at the door.Dammit. Entered the male toilet.Didn't turn back to look at the reaction of the guy behind me, nor look at the other guy who saw me coming out of the toilet, just rushed back up the stairs to the ladies.Luckily I didn't manage to see any guy peeing.
