I was in a rush as always, but this time it was for an important date I just couldn’t be late for! I found myself at a checkout counter behind an elderly woman seemingly in no hurry as she paid for her groceries. A PhD student with not a lot of money, I had hurried into the store to pick up some flowers. I was in a huge rush, thinking of my upcoming evening. I did not want to be late for this date.

We were in Boston, a place not always known for small conversation between strangers. The woman stopped unloading her basket and looked up at me. She smiled. It was a nice smile –warm and reassuring—and I returned her gift by smiling back.

“Must be a special lady, whoever it is that will be getting those beautiful flowers,” she said.

“Yes, she’s special,” I said, and then to my embarrassment, the words kept coming out.

“It’s only our second date, but somehow I am just having the feeling she’s ‘the one’. Jokingly, I added, “The only problem is that I can’t figure out why she’d want to date a guy like me.”

“Well, I think she’s very lucky to have a boyfriend who brings her such lovely flowers and who is obviously in love with her,” the woman said.” “My husband used to bring me flowers every week –even when times were tough and we didn’t have much money. Those were incredible days; he was very romantic and – of course – I miss him since he’s passed away.”

I paid for my flowers as she was gathering up her groceries. There was no doubt in my mind as I walked up to her. I touched her on the shoulder and said, “You were right, you know. These flowers are indeed for a very special lady.” I handed her the flowers and thanked her for such a nice conversation.

It took her a moment to realize that I was giving her the flowers I had just purchased. “You have a wonderful evening,” I said. I left her with a big smile and my heart warmed as I saw her smelling the beautiful flowers.

I remember being slightly late for my date that night and telling my girlfriend the above story. A couple of years later, when I finally worked up the courage to ask her to marry me, she told me that this story had helped to seal it for her –that was the night that I won her heart.
