Death at my grocery store

I saw death in line yesterday. Shifty. Challenging to be sure of features. Thin. Fade in, fade out, but not ever invisible. Walking and moving like the rest of us, but never speaking. Always changing positions, and smoothly moving from place to place, neither quickly nor slowly. Muted blacks and grays for clothing, with a flopping hood over his head and sometimes his face. For sure, a "he." No groceries actually were chosen or purchased. He breached social distancing guidelines next to me once, so perhaps I shall die soon, although he remained distant from me most of the time. I have promised my family to improve at staying safe.
