Warm welcome to Defence Forum of India, I believe everybody has to learn through the life as I am still learning from all respected members of the forum, this forum is like family and you are in right place if you are looking for fostering friendship and there are many your fellow countrymen are in this forum.
I can understand the loneliness you are feeling in a foreign land in foreign culture miles away from your motherland.
Stay cool, happy and sensible, and you'll make a lot of friends. We're generally a very tolerant bunch. Ignorance is not something we will hold against you- as long as it is not coupled with arrogance.
