Hello Young Lady - this is a very strange way to start a note to someone - especially your teacher! It sounds like a creeeeepy pick-up line.
Dear 'her name'
I just wanted you to know that I loved what you taught us on Thursday night. Frankly, I'd rather learn English in terms of grammar and writing styles than Literature because I've only been in the U.S for four years and I find it difficult to understand Lit. But I was just wondering if you could please provide me a link to "Power writing"?
