I realize this is a fictionalized story, but since you brought it up… Piro IS helping out at present. According to today’s strip, It’s not the mom requesting him, it’s Mom’s boyfriend. When I work in high schools, it’s not uncommon to encounter tired, sleepy kids who have been kept awake caring for younger siblings. So yes, it’s part of the family chores (although Piro may not be living at home) but it really can drag down a high school or college kid who is trying to pass, but cannot stay awake during class.
“Back Seat of a car” – The original discussion was about where to raise the kid, not where to create one.
