Yes, I am incredibly unfriendly when I’m trying to get my shit done. I want to be out of that place as fast as fucking possible. I don’t want to linger, I don’t want to chat, and I sure as fuck have never in my life been so distracted that a hundred other moving, talking people just vanished completely from my awareness. Is that some kind of ADHD thing? Some manifestation of executive dysfunction, like always being late and never letting anyone else talk in a conversation if they can’t actively shout over you?
It’s not just me. If I was literally the only other person in the store, sure, I could understand that, they thought they were alone, they weren’t expecting to encounter anyone else.
How the fuck do you just stop being aware of an entire seething mass of other humans flowing around you?
