I sometimes wish civilization as we know it would end.
Why do you wish for civilization to come to an end?
That'd be so cool! Then I'd get to live in the stone age like Fred Flintstone.
It might seem like fun in your imagination but you probably wouldn't really like living without modern civilization. I think civilization ending would be really terrible, and not nearly as fun as you imagine.
I just want to experience being a caveman. That would be very interesting.
If that's the case, then you should try going camping out in the wilderness. You could experience what it's like to live without modern technology, without civilization coming to an end. I'm sure you'd have a really fun and interesting experience.
