go ahead, hit me

ugh, i had a long hard day today. i feel like sean has been fighting me all day. not very many smiles today, mostly whining and crying. my patience was razor thin when nat got home. i told him about my rough day, and this was his response:

nat: you need to release some tension.
nat flexes his bicep, and turns his side toward me.
nat: hit me.
he points at the side of his upper arm that's flexed.
nat: right here. come on. do it. show me what you've got.
i begin wailing on his arm and stop when nat's arm got sore.
nat: don't you wish you were a guy so in high school you could do stuff like that [me punching his arm]?
