Writing dialogue within a story is something I rather enjoy. Perhaps it has something to do with watching a character come alive and develop a personality. I try to create dialogue that is as genuine and realistic as possible. It's not always easy to write out sentences that look as good when they're read as they would if spoken aloud. So often times my characters have many of the little speech habits I may have. Things like using the words "man" or "dude" are very common in my real life vocabulary. I've just always used them to emphasize and address, but not every one of my characters should be speaking like I do, so I try and pay attention to other people's speech patterns, in particular when watching movies.
Forcing myself to cut the healthy laugh short, I replied to Johnny's last statement. "Okay man, details. Let's hear them. Her boyfriend not showing up in the bathroom mirror?" I started to chuckle again but successfully held most of it back. Snot nearly shot out my nose in the attempt.
"It's not like that. That's a fallacy."
"It's not true. The whole vampires and mirrors thing. It doesn't work like that. That's all a myth."
"Yeah, myth is right." I started to laugh once more.
Johnny shook his head. "Angela brought him home for the Christmas Eve meal. He's cold. He's pale. He smells like coconuts, wears sunglasses, and he just stood at the door until my dad welcomed him in."
"So, a polite albino with good hygiene, standing in 30-degree weather who isn't a fan of being snow blind and you come up with vampire?"
Though it's meant to be lighthearted and humorous, depending on who reads this and how they read it, it could come across different than expected
