I notice something dark on the front of my white T-shirt, shaped sort of like a huge butterfly with wings spread. I try brushing it away, but it won’t come off. I touch it and my hands come away all sticky. I need to calm down, so consciously taking my time I slowly take off both my shirts. Under the flickering fluorescent light I realize what this is—darkish blood that’s seeped into the fabric. The blood’s still fresh, wet, and there’s lots of it.
