When adults are behaving like children, we occasionally tell them they’re acting like children. This rarely has the desired result of making the adult examine his or her behavior and correcting it, but typically makes them double down on the shouting rants that made us think the problem needed to be called to their attention in the first place.
Adults, anyhow, are capable of some pretty machiavellian bad stuff even when they’re behaving like adults.
And, as in today’s cartoon, it all begs the question “Behaving like an adult WHAT?”
Behaving like an adult human, I hope, is better than behaving like an adult jackass.
