This might be abnormal, but I find it weirdly sickening when people cry in public
Do you really? What do you do then when someone cries in public?
I will call the cops or hospital, either way I'm calling emergency numbers.
While it may be uncomfortable seeing someone cry in public, it is still incredibly sad for you to be so disturbed by it. It's not your problem, and they can cry if they want to, but you should just leave them alone and go about your day.
Maybe I could record the crying and post the video online and laugh about it.
That's a really insensitive thought. Think of how it would feel if someone posted an embarrassing video of you online just to have something to laugh about. Would you really want to make someone feel that bad?
