I saw an animal chasing my neighbor.
I looked out my window and spewed chunks of Crunchy Corn Bran out my nose. Mr. Dobber, my ornery neighbor with a penchant for wearing shorts, suspendars and black socks was running faster than a fat turkey on Thanksgiving. Which isn't very fast actually. But by the way Mr. Dobber was lifting his knees to his chest as he raced through our geraniums, it was obvious he was giving it all he had. And I would, too, if a large hairy llama with a dribbling slobbery tongue was chasing me.
To write good humor you need to avoid generalizations.
Use specific words.
Create specific scenes.
Design specific characters.
Do you find it hard or easy to be specific with your writing? Have you ever had a llama chase you? And if so, how did you feel about that?
