I was taught never to put a comma after AND or BUT because these conjunctions naturally tell the reader to take a breath. I stuck by this rule for years but now that creative writing is my hobby, I am often corrected. As an instance, this is how I would write the sentence below. And that is what they did, enjoyed the smells and the stillness and did not talk for a bit until Lady Vanderpump asked. “When will you retire?” I am sure I would be corrected for this. Please can you explain why I should put commas in?
