That may be it. Normally, I sort of forget that I stutter. I just finish my sentence and go on without giving it any thought. I only notice it when I catch a funny glance or a slight uncomfortable smile from the person I'm speaking with. It's typically a new person, since people who know me are used to it. I wonder if being around another stutterer makes me consciously acknowledge all the minor glitches and then when I try to suppress it, it just makes it worse.
