Thanks for the nice words, your writing is pretty good yourself.
Wanted to first say a few words about your situation if I may. Have you given some thought to where all these disrespectful behavior of hers come from? What is the root cause? Was I on the right track in my earlier post to say that jealousy on her part was driving it all? If so, you should know, or you may already know, that the resentment rooted in jealousy will come out from all angles, in things big or small. It's not a matter of whether she is going to go after you again, it's when. And you are not going to have a friend in her for a long time. So be prepared. Further, accept it as an ongoing challenge. When you do so, it helps you stay calm, and more in control with her. That being said, have a little understanding of her resentment may help you truly be the bigger person in this relationship. Put yourself in her shoes, you may just feel the same resentment towards the young kid who comes to your work and take over :-). She is not a smart cookie in the sense that she doesn't know how to manage that feeling so it won't come out so obviously. But then again jealousy is a very strong emotion and hard to contain.
Anyhow, back to your Q.
Regarding my writing skill, not sure I really have any good tips other than never-stop-working-on-it :-(.. sounds lame I know. Pay attention to anything you write, formal or informal, and always try to see if you can do better whether its structure or choice of words or anything you care. Study the good examples of writing that you have (I usually use the writings by a few excellent communicators at work as my material) and go over them sentence by sentence. Compare what you would have come up vs. how they phrased, make a note of the difference and adopt their expressions. I do this almost everyday partly because writing skill, as well as other aspects of the communication skill, is not a luxury but necessity for my work. I have no choice if I want to do an ok job. But at the same I enjoy working on this skills. Huffington Post is another good source of materials I like to mull over on weekends for their writing style. I am sure you have yours.
