Special Secret Us Knowledge.
Everyone is always coming up to one of us and asking questions. Many times we've joked that we must have a sticker on our forehead that says "Ask Me!! Let me drop all my problems so I can solve your problems!". Not that we mind in the least, its just that we don't really understand it.
Well, last night, LazyPhil and I figured it out. The "Special Secret Us Knowledge" is really just common sense, logic, reading and remembering what we read. I guess we just know a lot... well, ok, I guess my siblings know a lot, and people just ask me to be nice. :)
