in high school, I learned that there should be at least 3 sentences per paragraph. But I feel like, in writing fiction, you are allowed to do less, so there are only one or two sentences in a paragraph. But I'm not sure, and when I'm reading, I always forget to look. I know there can be tons of sentences in a paragraph because some books will have paragraphs go on for a whole page. But what is the minimum, or is there a minimum? thanks!
