Why do you have to write in English doesn't your boss understand over national language HINDI, which is older and well heeled then english and is much sweeter then English.
Why people in India think writing and conversing in English is the best god given gift.
Don't degrade you your self write it in Hindi and if your boss does not understand tell him that he is illiterate and needs to go to school.
If he can read Hindi then tell him to translate it in english.
Tell him you have pride in your language.
