The showers in my daughter's dorm turned scalding hot whenever a toilet was flushed. To warn others, residents would yell out, "Flushing!" each time they flushed the toilets.

During one of my daughter's visits home, a friend stopped by to chat for a while. I was explaining how my daughter was acting more distant now that she was in college, and that she didn't tell me all about her life the way she used to.

Suddenly we heard my daughter call out from the bathroom, "Flushing!"

"Wow!" said my friend, "How much more do you want to know?"
