I speak three languages too.
mother lauguage: Chinese
the first foreign language: English (studied for 8 years)
the second foreign language: Japanese (studied for 5 years)
Due to I majored in Japanese at university and worked in Panasonic for about 2 years after graduation. Now my Japanese is much better actually. So it's time to practice English.
BTW. How do you know Hindi? Are you an Indian or working in India?
