I'm walking the halls and a cow orker says "what's wrong?" Nothing's wrong! I guess my brow is furrowed and I look deep in thought. Well, I am. I have pics of me as a little girl, crease between the eyes, gazing off. Probably reflecting on every little thing I did or said and making sure I did or said it right.
And I had a bit of echolalia as a kid. I remember I would say a sentence, then immediately whisper it to myself to make sure it sounded right.
To paraphrase Spinal Tap: a little TOO much fucking introspection, if you ask me.
