Christmas Greeting From Who?

Yesterday I got a Christmas card from someone living in Green Forest. I have been getting a card from them for several years. Seems like 5 so it is probably 10. I don't know them. They were not in my class during school days at Green Forest. I think this person thinks I am Helen and is sending a card. Their memory must have faded like mine. The first year I thought, "how nice". I sent a card back. By the second year, my brain had cleared and I thought, "how stupid. I don't even know you" and threw the card away and have never sent one again. Well, the card still comes each year. The bearer calls me by my first name. I may send a card back this year and say, "who in the world are you?" Or better yet, I have Helen's address--after receiving the note to mail for Benjamin. I may just forward the card on to Helen!
