My speech is much more colorful (I don't mean in a dirty foul-mouthed way) in Bengali than any of the other languages I speak - I can express nuances while maintaining a style that I cannot in another language I speak without losing either the style or the nuance. I find Hindi is also very expressive that way. For the lack of a better word, I feel I'm unable to be equally "juicy" in English. Of course, I'm not a native English speaker so probably the limitation is me and not the language.
