I was once told that paragraphs should contain anywhere around 4-10 sentences, even if they're stories. XD BUt then a few years later once i got to high school, i was told paragraphs can be as long or as short as you want them to be, as long as everything makes sense. XD
Thanks for that. This has always annoyed me.
Besides, if everyone wrote the same way reading would be oh so very boring.
