I’ll never understand this

So my best friend is coming to visit me here in a couple days, and I’ve been cleaning my house. One thing that has always baffled me, is the concept of dust. How exactly does something get dirty by… not doing anything? Like I can somewhat understand my bottom shelves getting dustier because it’s getting kicked up by my walking and it settles on the shelves, I suppose. But what about people’s attics? How are things getting dusty there, when there’s nothing agitating the airflow there? There’s no humans shedding skin cells that get piled up on the items there. Why do attics get so dusty? I’ve just never understood it.

I saw something which said that people should dust the surfaces in their house about once a week, and I guess they weren’t kidding. I just wish that I could turn on my ceiling fan after not using it all winter, and not have to first spend 10 minutes cleaning it off. There’s much more important things going on in the world. I don’t want to have to worry that my things are getting dirty despite my not touching them for months. Actually not “despite.” Because of.
