A mother crab was watching her son walk towards her when she asked him why he always walked sideways. “You should always try to walk forward with your toes straight out” she scolded him, embarrassed by her sons silly antics.
But the young crab did not know how to walk straight, since he had never seen so. “Show me how to walk mother” he requested.
When his mother got up to walk, she was unable to walk straight no matter how hard she tried. She wobbled and hobbled, but almost toppled over in her attempts to walk straight, yet to no avail.
Now she understood how unfair it was to ask her son to do something for which she could not serve as an example.
