I hate them. From October to January I am a total fun sponge. I end up not going to parties and if I do go its a two drink minimum before I go so that I am not such an #$$.
Thanksgiving is just a big get together to celebrate excess. I would prefer to have turkey sandwiches and give the money that would have been spent to a homeless shelter or women's shelter.
Christmas... man do not get me started. I hate that #$%# holiday with all my soul. It should burn. If you want to celebrate the birth of your Deity do it when he/she/it was born, not during the time that the institution tells you that person was born so that they can compete with "pagan" religions of the day.
In short, I would prefer to spend time off with my family being thankful for the time that we spent, the time we have and the memories that we have gathered. Why do we need a holiday for that and why for goodness sake do we need to spend inordinate amounts of money to do so?
I await your flaming.
