I'm trying to talk to my kids in Japanese, because I'm not a pro English speaker. My wife speaks to them in English. That's her first language. I don't want my kids to feel the same as me when I was studying English. It was so frustrating.

By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.
