...When you've actually succumbed into climbing in the bath tub, fully clothed, to wrestle your tantrum throwing 4 year old into washing the conditioner out of her hair....then you hear something.
Sounds like sanding.
"What is that?" you ask yourself.
You, then, look over to see your barely one year old holding onto the side of the tub, grinding her teeth off with a foot file.
Little white teeth grindings smear the black emery board file, making it look gray.
Hopefully she'll be one of those kids who lose their baby teeth early.
