i'm at a public library and i don't know what to think. weird little things keep happening like someone coughs, and it sounds like it's over a PA system because of where they are in the room acoustically (i guess). or like, seven different people have been making grunting/groaning/moaning noises, or breathing like zombies. and, there are a lot of people here but not one of them even has a book with them. i keep noticing people looking at me sideways because i can see the whites of their eyes. it mostly just feels like a big waiting room. like, no one seems to be doing anything particularly important to them. i don't know whether this is bumming me out or if it is making me feel powerful because i get to be in stealth productivity mode.
earplugs would be perfect for your situation
