I am Indian too and would say the same that Indians like to be within their own click and celebrate Diwali, Holi, Ganpati, etc. I dont belong to that religion and dont celebrate those festivals so didnt care about celebrating them anyway. i wanted to integrate and learn about new cultures that I would not get in India.
I wanted to brush up on the French I learnt in college so i decided to speak to my classmate in French. She told me that if I wanted to learn French, I should take classes. She had come to improve her english and not teach someone else french. So that's when i decided that if i wanted to integrate, I would have be miles away from people from my country.
