It occurs to me that lot of folk skipped the lessons in English class on how to write dialogue.  You'd think, though, from reading books online or in print that one would pick up on how it is done.  Alas, nope.  I've seen a few stories that the dialogue is so jacked up one person commented it looked like a text string.

Another person wrote a story and I thought I was reading a play.  Only there was no emotion and no indication of what the characters' thoughts or feelings were.

Example

(cara)....blah blah.  Sam said come to breakfast.

okay. (me)

(cara) hurry up slow poke.

(me)  I'm coming.  Jeez.  I got out of bed and went to the bathroom.....then I went in the kitchen.  (Sam) bout time you came down.  (me) yeah yeah.  Rolled my eyes.

Whut de fuq iz dis?!   What de ras!    Basura!

That kind of crap is hard on the eyes much like block writing with no punctuation.  When I load up a book and see it, delete!

My contribution to the cause.
