Thank you for bringing this point up. I totally agree with Ghumante. This is not anti-Indian sentiments that we are talking about, it is more about our own culture. I was really ashamed when one of my Nepali friend at my work proudly told every body in the meeting " Diwali is one of our biggest festival and we do this thing called Rangoli and blaha blaha blaha." And funny thing this Indian manager replied her with a smile, as it happened his wife is Nepali, that he has been in Nepal and how he saw Tihar been celebrated in Nepal, and told her about laxmi puja the way we do. He used the word "Tihar". This guy Knew more than this dumb ass girl.
I mean even you go to India, Different states celebrate in different ways. This rangoli in Diwali and Rakhi is not something that we do at all. I get surprised when people put these pictures in the Facebook. Some people think they are doing something big by doing this. I am just waiting for that day when some Nepali dumb ass will start calling Bhai Tika as Bhai Dhoj. God!
