I only saw him a few times, but he had this habit of saying "this piece". As in "Okay so there's an A-Piece." or "So we've got some XYZ pieces".
Insert my head tilt.
A year later... The habit is making sense. Pieces. Yeah. Different pieces interacting to form the whole. Dealing with one piece here, another piece here, repeat repeat repeat, because certain things are etched into multiple pieces in different ways. How the pieces fit together. Light. Bulb. OMFG. This I can wrap my head around. This makes sense. I often wish I could have seen him longer. Grateful as hell for the times I got to, though.
