After stopping off for lunch on a day trip, an elderly couple had driven 10 miles down the road when the woman remembered that she had left her glasses at the restaurant. 

Her husband was irritated at having to go back for them. “How could you forget your glasses?“ He moaned. “ This is going to add an hour to the journey. The whole day is wasted!”

He was still complaining when they pulled up again outside the restaurant. As his wife got out of the car, he grumbled: “While you’re in there, you may as well get my hat too.”
