Just wanted to pay it forward

My friend and I met for lunch one day when we both had a day off together. We were chatting with the waitress and as I looked off I saw an old man sitting alone. He looked worn out, tired and sad. The waitress informed me that he and his wife used to come for lunch weekly and that she had suddenly passed away. I asked her to ask him if he’d like to join my friend and I for lunch, he looked over at me and softly declined, and when his food arrived, he ate alone. So of course without hesitation, I told the server I wanted his check. When he was done he stopped by our table and said, “do I know you?” I said “no, I just wanted to pay it forward and I choose you. Maybe we’ll see you again.” – Robin
