My four years old son stuck out his hand and said,

“Look at the fly I killed, Mommy.”

Since he was eating a juicy pickle at the time, I thrust his contaminated hands under the faucet and washed them with antibacterial soap. After sitting him down to finish his pickle, I asked, with a touch of awe,

“How did you kill that fly all by yourself?”

Between bites, he said,

“I hit it with my pickle Mommy.”
