What Is a Boy?

Between the innocence of babyhood and the seriousness of manhood we find a delightful creature called a “boy”. Boys come in different sizes, weights, and colors, but all boys have the same belief: to enjoy every second of every minute of every hour of every day and to fill the air with noise until the adult males pack them off to bed at night.

Boys are found everywhere-on top of, under, inside of, climbing on, swinging from, running around, or jumping to. Mothers spoil them, little girls hate them, older sisters and brothers love them, and God protects them. A boy is TRUTH with dirt on its face, BEAUTY with a cut on its finger, WISDOM with chocolate in its hair, and the HOPE of the future with a snake in its pocket.

When you are busy, a boy is a trouble – maker and a noise. When you want him to make a good impression, his brain turns to jelly or else he becomes a wild creature bent on destroying the world and himself with it.

A boy is a mixture – he has the stomach of a horse, the digestion of stones and sand, the energy of an atomic bomb, the curiosity of a cat, the imagination of a superman, the shyness of a sweet girl, the brave nature of a bull, the violence of a firecracker, but when you ask him to make something, he has five thumbs on each hand.

He likes ice cream, knives, saws, Christmas, comic books, woods, water (in its natural habitat), large animals, Dad, trains, Saturday mornings, and fire engines. He is not much for Sunday schools, company, schools, books without pictures, music lessons, neckties, barbers, girls, overcoats, adults, or bedtime.

Nobody else is so early to rise, or so late to supper. Nobody else gets so much fun out of trees, dogs, and breezes. Nobody else can put into one pocket a rusty knife, a half eaten apple, a three-feet rope, six cents and some unknown things.

A boy is a magical creature – he is your headache but when you come home at night with only destroyed pieces of your hopes and dreams, he can mend them like new with two magic words, “Hi, Dad!”
