If a fly or a bee comes into the house and one points it back toward the window or door through which it entered, most of the time, it exits. I have experienced this over and over again across the twenty years of living on the west coast. Others have said the same thing. I think it has to do with the temperate climate and open doors and windows and only occasional screens; insects learn "oops" and go back out.
This bee must have come in just before I was going out and, unfortunately, closed the window.
I did not notice it here, on the fibre, on the spindle, until I picked up the spindle intending to spin.
At first I thought it a spot of yellow that I had somehow spun. But no, it was the pollen. And then I saw the bee.
The bee was dead. It was too late to offer it an open window.
That it settled on the spun fleece both saddens and comforts me.
