You are driving north on Lincoln in downtown Spokane, in the farthest right lane.
You have just passed Riverside. A driver in your lane just ahead of you has stopped, clearly intending to back into a curbside parking space.
So you stop, too, leaving plenty of room for him or her to proceed.
Going around the car about to park seems iffy as traffic is still whizzing by in the lane to your left. So you just wait.
This is just going to take a second, so it's certainly no big deal.
But then the people in the car immediately behind you honk their horn at you — as if you are just stopped for no good reason.
Of course, by the time you resume your forward progress, there will be no sign of why you were stopped in the first place.
But couldn't the people behind you have figured it out?
