A disarming smile

Ugh. Sometimes I get so wound up and anxious in one-on-one interactions that I just start talking uncontrollably. There is very little filter between my head and my mouth. I speak in a total stream of consciousness kind of fashion interspersed with song lyrics, talking to myself, and meta-comments about the interaction taking place (e.g., "Oh, my God. Do you hear how I'm talking right now? I'm just telling you these random things..."). It must be quite a sight to witness when I'm really at maximum speed, and I imagine it must be overwhelming for the person on the receiving end. I mentally step outside of myself and think, "Shut up, shut up, shut up!" Then, when I proceed to keep talking, I mentally slap my head and groan.
