You know what I just thought about?

Okay, so imagine you've felt so much that you just don't care about anything anymore, in the way that if someone puts a gun to your head, you don't give a damn. And if someone laughs at you (better example xD), you don't care. And that you're not afraid of doing whatever you want to do (also a way better example than the first one :P). Then how is it possible that pain still exists? How can you still be hurt, even when you don't care? I DON'T GET IT. ;-; I think some people have had such a day when you just don't care, but they can still be hurt and I don't get why. Iiiiiiii have to stop thinking now, I should never think about things in life. ._. I mean I shouldn't think about why I look the way I do, how big the universe is, what happens when you die, if there's some sort of God or if this world is actually like the Sims. Yes, yes I used to believe that this world was just the Sims for another world, DON'T ASK ME WHY. x)
