A boys rule

I was holding Elizabeth and happened to notice her bangs looked a little funny. Upon closer inspection, it looked like there was a small chunk that had been cut. I decided to interogate Ian.

"Ian, did you cut Elizabeth's hair?"

"No."

"Remember, you get in less trouble if you just tell the truth. Did you cut her hair?"

"Oh, no!" he said. "I would never cut a ladies' hair. That is a boys rule: you don't cut girls' hair!"
