I don’t understand what makes me mad on public transportation. I was in the bus tunnel* and there was a metal grate loose. Some teenager was standing on and off it and making noise. It should have annoyed me but I didn’t notice it until someone started yelling at him. And I was much more upset with yelling guy than clanging guy. I would have thought that I would be equally, or nearly equally, upset with both. I had to stifle a laugh when clanging guy started clanging again with yelling guy walking away.
* I still call it that.
