"Dad, you know what will be quiet and won't make a mess?" asked Master7 eagerly.
"Let's see. Knowing you, it's got two letters - I'm guessing the first one is a D and the second one is an S. Am I right?"
"Maybe," he grinned at me. Master7 can't get enough of his DS console. We make sure of that.
"Well, my answer has two letters," I told him. "Can you guess what they are?"
"Umm, N and O?"
"That's right. Now go outside and play."
"I've got two letters for you, Dad," he called back over his shoulder. "O and K."
I wanted to say I had two letters for him, P + O, but I held it in. Good parenting is all about restraint. Besides, he was long gone.
