SH: You opened that new box of cereal!
SH: But you’re supposed to finish the other boxes that are already open first.
Me: Says who?
SH: It’s the right thing to do. Didn’t your mother teach you?
Me: I don’t care. I wanted this cereal.
SH: If we had kids, would you let them open the new boxes before finishing the old ones?
SH: Would you open the new box?
SH: What if the kid said, “How come you get to open it and I don’t?”
Me: I’d say, “When you’re paying the mortgage and buying the groceries, you can open whatever you want.”
SH: But that’s different rules for kids and for grownups.
Me: So what?
