A certain student was habitually late for class.
After several weeks, his frustrated teacher finally said, “Your tardiness is hindering your educational experience, the next time you walk into class late I will have to give you a detention.”
The next day he was late once again. He crawled in through the doorway, surprising the teacher.
Looking at him sternly, she said, “Since you’re late, you’re going to have to go to detention.”
