R has been complaining of a headache all day, so I give him Tylenol.
R – This medicine tastes yummy!
A few minutes later, B follows me into the bathroom.
B – Mommy, I have a cough.
Mom, suspecting he wants some of the yummy medicine himself – No, you don’t.
B – Yes, I do.
Mom – Well, this medicine won’t make your cough any better.
B – I know. I’m just warning you.
