I was having a conversation with my son this evening about just this topic.
He said he came in after work and sat down. After a few minutes he said to himself "damn, dad's eating too loud." and then "damn Jerry's typing too loud." And then he realized that the problem was all within him. Everything was pissing him off. I told him I've essentially been apathetic about pretty much everything for the last two days. I didn't know why but I just had pretty much no fucks to give. This piece paints the picture quite well. And we're all feeling it right now.
