I live on the Yamanote train line. I see people rush to get on the train, running full force. And if they miss the train a dark cloud crosses their faces, as if they failed at life. Come on people, the trains on the Yamanote line come litterally every three minutes! Missing a train is no big deal.
Sometimes people get mad at me for things I have no possible way to change. I was drinking with a Japanese friend and she started to get upset because I was genetically American. Genetics are something that are fixed in stone. Get angry about it all you want, but its not gonna change.
Often when I'm in a public restroom stall people come up and knock on the door to 'check' if I'm inside. How could the stall be closed and locked if I wasnt inside? Don't get it, but I guess maybe they are saying hurry up. But I still think its odd.
