I've been away (visiting my son, his wife, and my grandson) for a week.
Jan, earlier you asked me why I didn't like dialogue tags. Well, I had grown up fascinated by words, especially adjectives and adverbs, but in the last few years, I've learned that they bog down my writing. I've learned that "said" is an invisible tag - meaning it doesn't distract the reader from the dialogue but adding more (and sometimes confusing) detail. I saw a short story written with only dialogue once and decided to try my hand at it.
This was my first ever Challenge entry and I got an EC...SHOCK!!
(excuse the lack of space between lines... I didn't know)

I find the trick to doing this is to include direct address occasionally, so we know who is speaking to whom. Also, the style of speech and what they are saying also gives clues. This is a rather long piece, but I often include shorter sections of un-tagged dialogue in my writing.
