Am is all to be all
A police car pulls up in front of grandma's house and grandpa gets out.The polite policeman explains to grandma that the poor gentleman was lost in the park and couldn't find his way home.
'Oh dear,' says grandma. 'You've been going to that park for over thirty years.How could you get lost?'
Leaning close to grandma,so that the policeman can't hear, grandpa whispers....
''I wasn't lost. I was just too tired to walk home."
