Dom, you can definitely write something you have no experience with... LOL I do that a lot

But then I do a lot of research into the topic...nail down vernaculars to make things sound more real etc.

What you show in you writing is that you do not have the nuanced understanding of your relationship.

THAT comes with experience....but keep trying....the hook is worth it

Maybe think sitcom plots to get ideas

Maybe a visual here...you took a sledgehammer and prybar to the marble instead of a chisel and mallet.

If writing ever becomes work I think I'm going to have to stop
