Every family, it seems, has its own set of words for describing particular Lego pieces. No one uses the official names. “Dad, please could you pass me that Brick 2x2?” No. In our house, it’ll always be: “Dad, please could you pass me that four-er?”

I began breaking up with legos the day they came with decals describing things like computer consoles.  It was my imagination, damnit.  My computer console could have been three three-dot pieces lined up on a bendy joint if I wanted it to be.  …In retrospect, I was already irritated with the usual user experiences.  Go figure.
