How many times does it take?

Last night in class I asked the students to turn to page 98. One student thought I said 198 and turned there. He asked me to confirm the page since 198 was the start of a chapter titled Understanding Pregnancy. In class last week he announced that his wife is pregnant with their twelfth child. He showed the chapter title to the person beside him who just laughed. She told the class, and I said, “Kelly, we just thought you may not have gotten it the first 11 times so this will help you the twelfth time!”
