I’ve worked at a few places now where I sit at a computer all day facing a wall or a corner with a wide open space behind me. If anyone wanted to come speak to me they really had no choice other than sneaking up behind me. It wasn’t too long before I could identify all the usual suspects by their walking or breathing patterns. If I asked them to stop by later to talk about a certain project I would open it up on my screen and have it ready for review by the time they got to my desk. “How’d you know it was me?” asked the foot shuffler that always had $5 in quarters in his pockets.
Also, come see me this weekend at NEWW2! Bring tiny pumpkins and I will draw on them.
