Multilingual people have a super brain. Those who don’t speak more than one language won’t understand the level of gear shifts that take place inside the brain. These people think in one language and speak in another. And when the it is required to be spoken in a 3rd language, the gear makes it’s final shift.
But there’s a problem. Smooth functioning of this process sometimes depends on the geographical location of the individual. In my case, it is a thing.
Apart from Bangla and English, I speak Hindustani (an utterly adulterated hindustani) When in Bengal, this language takes a funny turn. But when out of it, the fluency is unparalleled.
