Is it possible they awakened, or arrived, or whatever they do, over just one night?
The first surprising glow in the corner of the eye (did I just see that?) then another by the bird bath, then another back in the corner by the floppy hosta, and then a whole yard full, the green, just-mowed, fragrant yard oscillating and aglow, silent, pulsing and unexpected. Not last night, but tonight.
Last night a dream of shattered glass, wandering the house in that bellicose dark of 3 a.m., my telltale body goosebumped with fear. No sleep and the BBC up loud to scare away trouble.
Then tonight, first fireflies, dusk a velvet plush, and just like that it's summer.
