So, Im not trying to be rude or mean, but sometimes it really is the best way to get someone to realize "why the hell did I just say that? Do I have any evidence its true? Did someone tell me this? Does what I just said even make sense?"
Along those lines, yesterday, a cyclist passed me on the river road. I had my headphones on, but I heard him begin while coming up behind me, shouting "that's dangerous!" Then, "there's a lot of broken glass around here" as he passed me. OK, I'm sorry, but I unleashed my second mocking reply within a week. I told him as he sped away, "I know, this place is full of it, be careful you don't get a flat tire, fall over your handlebars and break your neck!" I don't know if he said anything more, by that time he would've been too far away to override my headphone music.
In other words, for some reason, he assumed the danger of broken glass only applied to me, not him, but really he would probably realize, if he thought about it rationally, that it doesn't pose much of a danger to either of us, otherwise we wouldn't be able to do what we do all the time. Or maybe he had seen some auto glass on the road left over from a fender-bender before getting on the bike/pedestrian path.
The funny thing is, I got stung by a bee on the bottom of my foot right at the beginning of my run, when I stood in the grass to the side of the asphalt path in order to put on my headphones. Two days before, my son got stung by a bee and had an allergic reaction, so we had to take him to urgent care. I just felt a few tingly jolts of venom but by the time I had found an old jam I wanted to listen to, it had passed, and I was able to do my six-mile run without any discomfort.
Now, if the cyclist had said, "be careful, the grass is full of bumble bees," he might've had a point.
