A strange story.

The other day, I was supposed to meet my friend in front of a public restroom. I heard a flushing sound from inside the men's restroom. So I figured someone must be in there, but even after about 30 minutes, nobody came out. However, about 10 people did go in. This situation is pretty scary, right? My friend, who showed up 30 minutes late for our meeting for no particular reason! At least apologize...
