Although Thanksgiving is a national holiday, for many of us, it's a time just to reflect on anything in our own lives we are grateful for... our families, friends, livelihoods, homes, making it through a difficult life experience and suddenly finding that something really good came out of it, good food, and great times. 
Now THAT is a holiday I wouldn't mind having go year 'round.  (Except maybe for the eating part!   )
