I started to wonder if Carl had suddenly passed the singularity last night.
Out of the blue he announced “Nodding No” and indeed panned his range sensor left and right in his “unh-uh” nodding no behavior.
My wife commented she didn’t know he could do that, and I explained “oh yes, he can also nod yes.”
But when I told Carl: “Hey Carl, Nod Yes”, he stubbornly refused to my embarrassment.
Digging in further, I discovered the tilt servo had frozen after eight years of non-use. Until his “Two for $6” servos arrive, Carl can only “Nod No”
