person A: I recently had an existential crisis. It was awful
person B: Oh no.  What happened?
person A: I watched the new Avengers movie and a lot of people die. And I realized we're all going to die and there's no way to know what that's like. And then I felt sick for a couple days and couldn't stop thinking about it
person B: Wow.  It had that much of an effect on you?  That it made you consider your own mortality?
person A: Yea. I don't know why_comma_ it was the dumbest thing. I was really upset.
person B: Well it's good to remember your mortality_comma_ even if you have to ignore it to continue normal life.
