That sounds almost like a treasure hunt! Very productive, at any rate, because at least the items aren’t Mathoms.
I worked part of a jigsaw puzzle while listening to an uplifting talk. My days always go better when I’m able to do that. The listening part, anyway. Sharon can’t understand how I can really listen if my hands are busy. Training. One part of my mind listens and the other part is resting.
I can do a lot of things while listening ... but not read or write, unless I’m writing notes about the lecture.
