"Best day of my life!"

My nights and mornings are filled with standard, brief, ritualistic-like greetings and banter:

“Good evening.”
“Have a good night.”
“Good morning.”
“Have a great day.”
“How’s it going?”
“Oh, it’s going.”
“How are you today?”
“Can’t complain.”
“I’m still breathing.”
“Working hard or hardly working?”
“What’s up?”
”Not much.”
“Don’t work too hard.”
“Another day, same old shit.”

But my favorite comes from a pleasant, cheerful older gentleman who comes in every morning for coffee and a newspaper. He is probably about 80. I always greet him with “Good morning, how are you today?”

His response is always the same:

“Best day of my life!”
