THE CRAB AND HIS MOTHER
Crab mom tells crab kid to walk straight. The kid laughs at her hypocrisy.
Don't be a hypocrite. Or maybe, don't deny your true nature.
This is the age-old battle between free will and determinism. Could the crab ever walk straight? That's not for me to say. I'm sure some crabs try to learn, though. Just like some humans try to get along with each other.
