Family traditions. When you are young you don't get traditions, when you are older you understand how precious they are. I think they are a way to hold on to where we came from or where our family comes from. Traditions help us realize who we used to be and what our culture means to us. It creates a feeling of belonging. You should watch Fiddler on the roof, this movie would explain the question you have asked.
Happy Thanksgiving to you and your family from mine
That is the feeling! If it is feel tradition is bad and will not keep, the other hand, if the tradition is good and some good idea, it will be keep and want to do some improvement.
