Scene #1- We pull up to the house and I go to unbuckle Timothy. He shows me how he fits his way-to-long thumb nail in between his lower teeth.
Me: Timothy let's not do that again, buddy. Your nail can break off and get stuck in your gums.
Scene #2- Twenty minutes later
Tim: Mommy I have a fingernail poking in my mouth.
Took forever to get the dumb nail out!
