A blue light glows I never saw before,
although I pay attention to what shows
on every inch of ceiling, wall and floor –
a blue light glows.

I can’t assume it’s new. I don’t suppose
a range hood can evolve or mutate – sure
I must have missed the sign its current flows?

Could some vibration shake or wake it more?
That theory’s not supported, heaven knows,
but something near has altered lately, for
a blue light glows.
