The pile of needles drew me to the center of the photo, to the mess of needles. It was visceral.
The image is uncomfortable. It immediately strikes me as a danger. Even though, upon further inspection, I can see the orange plastic covers on the tips of the needles, indicating a barrier and a level of safety, I have been socialized to think of needles, not only as a source of discomfort (receiving a shot), but also as a potentially life-threatening danger.
