Haha, we have a same Indian girl as well
When this girl was hired, she came to everybody's office everyday to say hi. This made everybody feel weird even she is a sweet girl.
Later on, she realized it and stopped it.
If the girl only says good-bye to the boss everyday, we may call her "brown nose" which is not a good reputation as well.
Just be yourself. You got hired by your skill sets but not your sweetness.
