Pretty fast...

Dear Nicky,

This evening we played some flash cards for a while, and you did really well. As long as you were into the game, you'd give me a color if I asked for it, a shape, or whatever. You did great. But you'd get bored fast, so I was always inventing a new game. Afterward we listened to some music, then went to bed. You're a smart and spirited little guy.

Love,
Dad
