Driving to Metro this morning I was squinting most of the way. It was full-on sun as I headed east. An early, low sun that slanted beneath my visor and almost blinded me at times.

I was counting on this sun, hoping it would warm the air and brighten the day. And it was complying. But it was doing it with such urgency that I felt within it the slow, sluggish air of July.

It was then — and later, as I loped around the block a couple times waiting for the bus — that I felt grateful for my sunglasses. When I put them on, the glare goes away, and I feel cooler, in more ways than one.

Even more than that, I feel protected, tucked away. As if the glasses screen me not just from the sun but from everything else, too.
