Linguistic tells for me

If you read/hear someone writing/typing like this, it's probably me
  1. "Most excellent"
    Many things are most excellent. This may mean that none of them are.
  2. I write in my head in a weird combination of English, Spanish, Japanese, and Quenya
    I sure that many polyglots think this way too. Code switching!
  3. Ending my sentences abruptly
    I don't usually do this, but
  4. "Am I to ...?"
    Where on earth did I pick this overly formal phrase up?
  5. Capitalizing Important Words
    Admittedly many people do this, but I've done it for years.
  6. Echolalia
    Excessive echolalia.
