I've been doing an overwhelming amount of polish edits lately before sending my manuscript off for review, and something I noticed myself doing (without even really thinking about it) is having my protagonist ask a funny question and answer it herself.
This technique works particularly well if you're writing in first person or third person close point of view.
For example, let's say your protagonist is walking out of a grocery store and sees a gruff woman slap her child in the arm and yell, "Stop hitting your brother!"
Your lead character could say something along the lines of, "Does technique really work for you? Talk about leading by example."
Now, I just came up with that off the top of my head, so I realize it's not that funny, but you still get the idea. And don't feel like you have to stick to question/answer format, either. Your answer doesn't have to be a real answer. It can be sarcastic or even a tangential type of answer.
Your turn! I want to hear your thoughts and questions. Do any of you brave souls even want to volunteer an example?
