When I was a kid i insisted in decorating our potted fir tree for Christmas - i was about 7 or 9 years old. Every year that i can remember i have celebrated Christmas, usually much more than i do Deepavalli. I was born right in the middle of Christmas and New Year! How can I not celebrate?
That's why i'm always jumping around decorating the office, home, planning christmas parties. and guess what i'm still Hindu and oh all my Christmas's have been vegetarian ;p
All you people mumbling about wishing people or whatever else nonsense, haish go play far far, its CHRISTMASSSSSSSSSSSSSSSSS ;p
