Ah. Idioms and their context. When that happens with me, I immediately search for the meaning/definitions. Then, repeated exposure helps. (this forum's a great help as I, not only can familiarize myself, I could also build up my vocab.)

And true, natives do have a way with their use of phrases that just goes directly to the point. They eliminate the use of redundant, unnecessary words and their sentence structure is just too.. [sigh]  

Anyway, as I have said, I doubt they'd offer to personally tutor/teach anyone for free. As that would be too time-consuming. Unless you're a close friend. So, either you just use the free tools and immerse yourself in the language/converse with them or

create a thread in services section and look for a private tutor with proper reward and all that. Goodluck.
