Return of the mask

I went for a walk today, first time leaving the house in 3 days due to work and rain. Hardly anyone was around, so I was unmasked apart from checking out a couple of shops. All was well, after an hour on my feet and a bit more on the clock, until, I sneezed! And my nose began to run, needing blowing! Had I gotten covid while buying food 3 days before, or was there another explanation?

Checking pollen websites, one said Grass: Low, while another said Grass: High. I don't know why the difference, but either way, grass has entered the field. And I'm sensitive.

So out came the mask again, and I left it on, apart from pulling it down to blow my nose. Which, after some unmeasured period, stopped being required, despite my still being among the grass and trees of a large park.

Woot, go masks.
