Two brothers, give or take six hours between school and bedtime, so many things to fight about.
Things like:
Who gets shotgun on the ride home.
Who got it last time.
Who had it all last week, for crissake.
Who left the empty Cheetos bag in the back seat for someone else to clean up (righteous indignation being best expressed by flinging said Cheetos bag into the way back – indicating that mom apparently is the “someone else”).
