"Sir, I may not be working here anymore," I said sadly, as I looked at him.

He turned to face me, but said nothing. He was a regular customer in his mid-50's, but I never got to know his name, even after working almost a year here.

I smiled widely at him, "I've just graduated."

He smiled back at me, and that was the moment that I knew that he was secretly happy for me, but yet a little sad that I was leaving.
