Start watching at around 3:20 and watch how happy they become as they sing until the end of the video.
If only everyone was okay with just sitting with their friends, singing. It's as if people forget that we're part of this strange, terrifying universe. We're all scared - everyone has a dense nucleus of fear inside of them, and I don't care who it is.
We should sing like this every night as if the world could end in a moment, as if we needed to bond together. The truth is that our individual worlds could end, and we do need to bond together.
