Americans consider it rude to ask questions about the person's appearance and disability. Americans and Koreans are the same. Actually, I don't know a single country that disagrees with this. All humans consider it rude. My dad was born with surname Rasp. He was adopted into the Arnold family. Yes, my birth certificate says Joseph Scott Arnold. I gave myself the Oatmeal nickname. Oatmeal is a cereal and tastes like a porridge. It's a little different than rice and other grains. Koreans should have middle names. They're making life harder to not do that. Ghetto Joe means cool gangster man.
