English Original
A man told his son to take a letter to the post office, buy a three-cent stamp, and mail it.
After a while, his son returned. The man asked him, "Did you mail the letter?"
His son replied, "Certainly, and I saved the three cents. I saw many people dropping letters into a box, so when nobody was looking, I dropped mine in too."
