Last year, around Labor Day, I read a "Happy Ad" in our local newspaper. There was a lady in a local nursing home, who was celebrating her 90th birthday and her family wanted everyone to know about it. It said that if you wanted to drop her a line(写信给她), here was her address. So I did.I found a birthday card and dropped her a short note, wishing her a happy birthday.
A week later, someone knocked at my front door. I opened the door and found a middle-aged man standing on my doorstep(门阶). He introduced himself as the son of this woman to whom I had sent the card. He explained that he just wanted to drop by in person and thank me for sending such a nice card. Apparently(显然)，like many older folks,she did not receive much mail and was quite excited to receive mine. I just didn't know what to say. I told him it was my pleasure and that I hoped his mom had enjoyed her birthday.
That year, I did not send out any Christmas cards, except to this lovely old lady in the nursing home. I just told her that I was thinking about her and hoped that she had a nice holiday. I sent her a holiday card and also a couple of notes in between. I just thought she might like to have someone write to get some mail.
A year later, I received a letter from her son, saying that his mom passed away a couple of weeks ago. He told me that my few little notes were enough to brighten a couple of her days here on the earth. Even though I never met this lady, but i did keep her and her family in my thoughts.
