You know you're growing up when....

Luke came running out of the bathroom, completely excited and almost out of breath.

"Mom! Great news!"
"What, bud?"
"I think being 9 means I'm growing up!"
"Yes, baby, it does."
"But mom, I have proof!"
"Proof?"
"Yes! Look!" He puts his face right in mine and is pointing up his nose. "I think I am getting nose hair!"
"Wow, Luke. How exciting." I say kind of sarcastically.
"I KNOW!" he exclaims as he runs to show the evidence to his dad. "DAD! You're NEVER going to believe THIS!"

Pure joy. Pure. Joy.
