A police car pulled up in front of grandma Bessie's house, and grandpa got out. The polite policeman explained that the elderly gentleman said that he was lost in the park and couldn't find his way home.
"Morris," said grandma, "You've been going to that park for over 30 years! How come you get lost today?"
Leaning close to grandma, so that the policeman couldn't hear, grandpa whispered,
"I wasn't lost. I was just too tired to walk home."
