by this traditon because this is one of the only times we all see eachother at the same time, which affects what we find important to us as a family member. While celebrating Thanksgiving, we always share old stories and memories from the past. This allows younger generations to understand the experiences their older family members have had.
I do not think this tradition can be considered art because of several reasons. I believe my family Thanksgiving is a very weak tradition, there is not much meaning in the event and it has becoming just a regular day that we get together and eat on. Also, I do not think most traditions could stand alone as art. The only exeption I would make is a religous ceremony with beautiful music and artwork within the venue. Personally I do not find tradition to be important, I think it is just a matter of preference if you find certain events to be that significant to you.
