In One fish, Two fish, Red fish, Blue fish, Dr. Seuss asks a question that traps any father who happens to be reading it to his kid(s):
Some are sad. And some are glad.
And some are very, very bad.
Why are they sad and glad and bad?
I do not know. Go ask your dad.
With that, I undid much of MMM Jr.’s progress in mastering pronouns.
