Mine is quite dusty, and I get a lot of spiders and webs, but I don't leave food rotting around or trash or stuff like that.
No one comes over and I'm mostly totally unbothered by dust. And cleaning is quite tedious because of unwieldy furniture and lots of objects that need moving.
My walls have also gone unpainted for too long and my windows are pretty dirty.
I wish I wasn't such a pig but cleaning is so tedious and unrewarding and there is always something more urgent or more fun to do. And it feels like even when I clean my room, the dust comes back nearly immediately.
