They definitely do in our house -
We celebrate Id with the Khans who are our next door neighbors. I take gifts for their grandchildren and Anirudh gets Idi from them.
We celebrate Lohri with out Sikh friends and they celebrate Sankranti with us.
We put up a Christmas tree for Christmas celebrations and my christian friends celebrate Diwali with us.
We all can stay together and be happy but only if we all want to! The decision is ours and don't we all know which is the better way? :)
