Chew Pen caps, Nail biting, mouthing what I just said after saying it, Somewhat random code-switching in my everyday speech. Those are just a few of the habits of mine that I seem to have been doing just in the past 15 minutes it seems.
As I'm typing this though, I'm somewhat mouthing the words of what I'm typing, but the strange part of it is I'm typing it in the English, And mouthing the words with my Dutch (Flemish). I'm sure that if I recorded some of the rituals of the day I would probably have a list that was at least 2 pages long. Now that I'm thinking about it, when I listen to music or watch a movie in a language that's not one of them that I am completely fluency in, my brain takes in the grammar/vocabulary/syntax/phonology, and somewhat cross-translates instead of actually thinking in that language itself.
