Nowhere near my worst co-worker, but still funny.

The Dev team were all in a separate glass walled room with the business & support staff out in a bigger room outside. As is our wont, we wore headphones while working a lot.

One of the non technical folks asked me why and I said it helps me focus by keeping out distracting noises.

"Oh, I thought you were listening to code or something"

😮

It was kind of an eye-opener as to how little clue a person sitting just 4 meters away had of what I did or how I did it. And actually it helped explain some confusing interactions...
