Tonight before bed:
Julian: "Mommy, I am growing a mustache, because I am a big boy."
Julian: "Yes. Mommy, why do boys grow mustaches?"
Me: "Um, because they are boys, and boys grow hair on their face."
Julian: "Mommy, why do you have a mustache?"
I have now realized it was not a good idea to bring Julian to my last waxing appointment.
