Thanksgiving

I don't know what Thanksgiving day is , it's origins, significance. I imagine (probably rightly) that it is a day where we thank all people who are responsible for what we are.
Let me try to do that for fun.
I thank my parents, life partner, friends, kids, relatives, teachers, colleagues, enemies, game developers, TV producers, sportsmen,... basically everybody for making my life a semi ineresting affair.:)
