Hairy underarms

Yesterday:

Hayden - Why do you have hair under your arms?

Justin - Huh?

Hayden - I don't have hair under my arms. Mommy doesn't have hair under her arms. No one I know has hair under their arms.

Justin - What should I do about that?

Hayden - Find out why you have hair under your arms!!!

Today:

JJ - I am going to have hair under my arms when I grow up

Hayden - I am going to have millions (pronounced mill-ee-uns) of hairs under my arms...but then I will shave them

JJ - Me too!
