- We dance pretty much the same way we always have, since our Earth has always been turning. In fact, we’d be in serious trouble if it stopped, so really, let’s not waste each other’s time with questions like this one. You might as well ask ‘how can we breathe while there’s still oxygen?’
- How do we sleep while our beds are burning? I’m going to go with ‘not in our beds’.
