If you're going to lie about what you said, it's best not to do it in a written conversation. This is the post I was replying to: You said there is no context in which you could ever use the abbreviation "math." You never said "there is no context in British English" or "there is no context, unless it is a convention of your local dialect." Most of my students that exhibit this kind of behavior are in the 4-7 year old class. Most people by age 8 (if not earlier) have learned that if someone sees you do something, you can't lie about it and expect them to believe you. Going back to what you said, particularly this part: By saying that it's not incorrect, you expressly implied that my previous explanation was wrong. You're putting words in my mouth. Words I did not say. You are assuming an implication that I specifically worded my post to avoid. But I should be used to that from you by now.
