kids: a nonlinear phenomenon

[sistawendy]

My son has had facial hair - patchy, teenage facial hair - for at least a year now. That means his mother & I have been reminding him to shave frequently, but not always effectively. Last night, as I dropped him off at home and kissed him good night, I didn't feel any stubble on his face. I couldn't contain my surprise. "You shaved!"
"Yeah, I had to look good for work."
"You're growing up."
He rolled his eyes as he walked in the house.
