When I was like 4 or 5, I loved those Sesame Street movies where Big Bird visits other countries. I really liked learning Japanese words in "Big Bird in Japan", but unfortunately almost all the words they focused on sounded exactly like English words: "hai" (yes) sounds like "hi", "ohayou" (good morning) sounds like "Ohio", and "ichi, ni, san" (one, two, three), sounds like "itchy, knee, sun." Because of this, I thought for a time that Japanese, and probably other languages besides English, had all the same words as English, but the meanings were just switched around.
