I was just now riding my bike back from grabbing lunch, and a homeless person threw some garbage at me from the sidewalk and yelled, "FUCK YOU, BITCH!" I was, needless to say, startled, and looked back and said, "Calm down, dude!" (Why did I say "dude"? I never say "dude." Anyway.) Another person who was walking by appeared to not enrage the homeless person/cause them to throw food. There is a good chance this person is still at the location from which they threw the food. Usually I'd call my mom and ask her what to do, but I think my dad's taking a nap right now. Should I call the nonemergency police line? The people at DESC who go check on homeless folks? I am not more than a little bit unsettled; my concern is only that the homeless person might try to throw garbage at someone else (maybe they have had some trauma surrounding female bike-riders) and possibly hurt them, and that the homeless person could use some help.
