Common activities means better friends
If you want to make new friends, there is no use in just saying hi to people, something of value should be exchanged or there should be a common activity. That’s when they become friends. Real friends.
I’ve added a page on my wiki to list the type of common activities possible in India right from cycling to movie appreciation. Let me know if I can add more variety to the given mix of activities. I’m interested in figuring out what activities do people take up.
