I always pick up languages quickly if they are being spoken around me. I think that the environment teaches us best. If you hear a particular language being spoken around you often and you are able to ask questions about particular words or phrases, it really helps. :grin:
My father is from India and my mother is Pakistani. They both speak one separate language and one common language. We grew up learning all 3 of these languages plus English. I am really thankful that they had done this. It's great to know these languages and always comes in handy. I have done the same with my daughters.
