Andy wears glasses. He doesn’t wear them all the time. He wears them when he drives his car. He wears them to read, and when he works on his computer.

Andy gets an email from the eye doctor’s office. The email says— We have not checked your eyes for one year. You should make an appointment. We will check your eyes.—-

Andy goes to the eye doctor’s office. He does an eye test.

The eye doctor says, “Your eyes are OK, but maybe you need new glasses. You need glasses that are a little stronger.”

Andy says, “OK.”

The eye doctor says she will order new glasses for Andy. She says, “Maybe your new glasses will feel a little bit strange. Maybe you will get a headache for a few days. Maybe you will feel ill for a little while.”

After one week, the eye doctor’s office calls Andy. The receptionist says, “Your new glasses are ready. Please come and get your new glasses.”

Andy goes to get his new glasses. His eye doctor is not there. She is on vacation.

Andy pays for his new glasses and takes them away. He is very pleased. His new glasses do not feel strange. He does not have a headache. He does not feel ill.

A few weeks later, Andy gets a call from his eye doctor. “Please come and see me,” she says.

Andy goes to see his eye doctor. She is very unhappy. She says, “I ordered your new glasses, but I made a big mistake. I asked the company to make your new glasses but the order was the same as your old glasses. So , there was no change. I am very sorry. I have ordered new glasses for you and of course, you will not pay anything.”

Andy is a very calm person. He says, “It’s OK. Don’t worry.”

The eye doctor says, “Didn’t you think it was strange when your ‘new’ glasses were the same as the old ones?”

Andy laughs. “I didn’t feel sick! I didn’t feel strange! I didn’t have a headache!. I thought ‘my eye doctor did a very good job!'”
