Fred is in his 90s. Fred gets his lunch delivered every day. I deliver twice a week.
Ring ring
Who is it?
I have your lunch. (place lunch on special platform by front door and backs away)
What is this?
It is your lunch!
Is it? Who are you?
I am delivering your lunch
Fred gazes at his lunch and me in bewilderment
What a surprise!!
This happens EVERY DAY
