The middle one said to me this evening, "Mommy, have you ever heard of the tripod grip?"
"No, baby, I've never heard of that. What is it?"
"Well, it's like this. It's how you're supposed to hold your pencil. You're doing it wrong."
Apparently, I hold my pencil the wrong way. First my teachers, now my daughter. It's been working for me for thirty-something years. So sorry.
