(I am having a terrible day at work, and haven’t smiled once. I have just finished ringing up an older couple’s order.)

Me: “Have a good day.”

Older Customer: “Do you have any paper?”

(I give the customer some receipt paper. He gets a pen, quickly scribbles something on the paper, and hands it to me.)

Older Customer: “Everyone deserves to smile.”

(The customer then walked away. I looked at it and he had drawn me a flower. I still have it. )
