Please remember what Thanksgiving is about: giving thanks to those who help us, and thanks to whatever you believe is responsible for your life and health and good fortune. Whether you celebrate the day with family or friends or by yourself take a moment to say thanks to someone or to whatever you believe in.
Everyday is Thanksgiving for me because every day I thank the family that thought of others when their child died in an accident and donated their child's organs. If you have never been in the position of needing a gift of life be thankful for that too.
Those who receive the thanks of others are indeed very rich people. Those who generously thank others are fortunate that there are those they can thank.
