A few days ago I was sitting in a Thai restaurant enjoying a meal when I got a phone call from a friend I hadn't spoken to for a long time. Full of enthusiasm and excitement I talked slightly louder than usual and in Spanish, my mother tongue.

　　A few minutes into the call the lady sitting beside me got up, seemingly upset, and asked the restaurant staff to relocate her to a table as far away as possible from "this man who won't get off his phone"

　　I sank in my seat out of embarrassment. I ended the call soon afterwards and felt the urge to go over and apologize. Before getting up I looked around to see where she was and I found she was, indeed, at the table furthest away from me. I noticed that the lady was alone and staring out of the window, looking a bit sad.

　　Right then I quit my plan for a conventional apologetic gesture and decided to conduct an experiment. Seeing those funny smile cards in my wallet, I took one out. When signing my check I asked the waiter to secretly charge the lady's meal to my credit card instead of her bill.

　　I left the restaurant, letting the waiter know I would be back in a few hours to pick up my credit card. I returned later as promised, excited to learn the result.

　　To my pleasant surprise, things turned out the best possible way. A group of restaurant staff approached me with joy, telling me that the lady had dined there many times, but they had never seen her smile and laugh like she did upon receiving the smile card and the $0 check.
