Time to get the baby book out for a special milestone: Dexter's first lie.
Me: Dexter! Come here, buddy, time to get shoes on.
(he turns around and crawls up the stairs)
Me: (chasing after him and carrying him back downstairs to get shoes on) Dexter, you need to listen to Mommy. I know you heard me tell you to come downstairs and get shoes on.
Dexter: No Mommy, I was upside-down. I couldn't hear you!
I think he maybe meant to say he was upstairs not upside-down but either way it was most definitely a purposeful (though very cute) lie.
I didn't have a picture of him in the act of lying, so here's one of him being goofy at preschool.
