I made a remark to my wife yesterday that I never went to kindergarten. The school district that I lived in did not have a kindergarten class at that time.
She replied, "That's why you don't know everything you need to know."
See Robert Fulghum, author of "All I Really Need to Know I Learned in Kindergarten." Speaking of Robert Fulghum, you might enjoy his essay, "The Way of Nude Food".
