...by Truman Capote.
This one is technically a short story--actually, you can get the entire text online here: http://www.geocities.com/cyber_explorer99/capotechristmas.html
I think. Unless I'm missing something...
Anyway, here's a synopsis from Amazon.com:
A Christmas Memory is the classic memoir of Truman Capote's childhood in rural Alabama. Until he was ten years old, Capote lived with distant relatives. This book is an autobiographical story of those years and his frank and fond memories of one of his cousins, Miss Sook Faulk.
Thanks for the submission, Sharon!
