Before the main post, 2 facts about myself: 1. I am learning Chinese and Japanese 2. Unlike the stereotypical version of a white American, I can usually tell the difference between East Asian nationalities just by looking at them. Anyhow, I have a neighbor who's East Asian. For some reason, I thought he was Japanese. I saw him tonight and greeted him in Japanese,"Kombanwa". He gave me a nasty Look and I realized my mistake: He was in fact, Chinese. He must think I'm a total racist! What do I do? Also, was it racist of me to try to greet him in Japanese seeing as I thought he was Japanese?
