Wish me Luck as you wave me goodbye

As I was on my way to lodge some monies into the bank, I was walking down the street and smoking a cigarette.

An elderly man coming from the opposite direction pointed at me with his bony finger and said "You're too young to be smoking!".
"Really?" I said surprised "nobody ever told me that before."
"Well, you might be, and you don't seem to have much money" he stated.
"Why would you say that?"
"Because you're all in the red," he explained pointing at my sweater.
We laughed. "It might be quite true, actually" I confessed.
"Well, either way, you might not have much money, but you still have your sense of humour!" he said and then, to my astonishment, he broke into a song
"Wish me luck as you wave me goodbye..." he sang while walking away.

I stood there for a while, frozen. My life is surreal. I should get used to that, right?
