If you feel uncomfortable, you can stay by yourself in a corner. Most of us would feel uncomfortable, so we would all stay by ourselves in a corner. Now, do you see what the problem is? Exactly. In order of us to stay alone in a corner, we would need a lot of corners. If there were only four, as usual, the fifth person who felt uncomfortable would have no free corners to choose. We would need to party in a room with at least 50 corners.
Where do you find such a room? That's why we can't really get together.
