When you tell a story, try to escalate it and surprise the other person. Exaggeration works only if you take your interlocutor by surprise and turn your story around unexpectedly.
Then, be as specific as you can. When you introduce elements such as colors, details about a place, a smell, a sound, or anything else that can give life to your tale, you make it easier for your readers to understand you, as you’re building up a mental image for them.
