What are the misconceptions of non-tech folks when working with devs on web projects?

I am preparing a blog post for non-tech folks to manage their expectations but also explain how we work. For instance, I will mention that the idea of "simple" tasks is different when it comes to code (centering on PWA being an example), or that if they send us a text, oftentimes it's not just "copying and pasting it".

What are the biggest misconceptions you think non-techies have about web dev?
