"I'm going to go ride my bike," my eleven-year-old son announced.
"Okay," I said. "Have fun."
About twenty minutes later, I heard a ridiculous amount of noise. I looked up and saw my boy and his friends coming down the street on their bikes. The noise was coming from their bikes. They sounded like a twenty-person motorcycle gang.
When they pulled in the driveway I walked over to ascertain what was causing this din. I found plastic cups rigged to the bikes' fenders which hit the wheel spokes as the bikes were pedaled. "Seriously?" I asked. "What were you guys thinking?"
My son grinned. "We're thinking motor bikes are way cooler than regular bikes. Do you like them?"
I shook my head. "You get an A+ for creativity, but an F for being respectable citizens. You'd better take those things off before someone calls the police because you guys are disturbing the peace!"
