Old timer showed me a trick with a pencil and a pack of gum
Back in 2009 I was doing trim in a house outside Austin. Old cabinet guy, must've been 70, watched me struggle fitting a scribe for like 10 minutes. He didn't say anything, just walked over, grabbed a #2 pencil, and marked the back of the piece by dragging it along the wall. Then he popped a piece of gum in his mouth and said, "The wall ain't straight, so your cut shouldn't be either." That one line stuck with me more than any class I took. Still scribe that way today. Anyone else have a moment like that where a stranger just dropped some knowledge on you mid-job?
