Your days are numbered

In between my swinging sessions, I sat down on a bench for a smoke... staring at this pigeon leisurely walking by....

"Your days are numbered." So said the voice.

"What?"

"Your days are numbered."

"What are you talking about? The psychic said I have a long life to live..." Oops... to the voice I protested and responded.

Then I thought to myself... gotta finish whatever I need to finish then...

And, the pigeon walked on... 8-O lol
