Talkers

Recently with friends we had a discussion about "close" talkers and "low" talkers. I'd like to add another entry to this group of people whose talking habits annoy others....The "one word ahead" talkers. This group seems to surface in church where they always have to be one word ahead during any of the group prayers or responses. Anyone else ever sat by a "one word ahead" talker? Are they just trying to hurry the mass along?
