Do as I say not as I do

Last night we had the grand daughters for the evening while Mommy and Daddy's schedules overlapped. Our three daughters were down stairs with the oldest granddaughter and I hear Macey, our youngest, say

"TRISTAN, Dont do that! Tristan, 1 ...... 2...... Don't let me get to 3??"

Uhhh where do you think she's heard that? Her daddy really should watch what he says (Giggle....ok...ok..it's not ONLY him).
