Youth is surprising. One morning We wake up, and part of Us has grown! Was like that, now like this! The shifts grab our attention when We notice, which is not all the time (another feature of Youth).
Rhinos are never certain, even after 50 million years of wondering about it, whether We grow inside, making the outside stretch, or the outside grows and the inside has too hustle to fill it up…?
We don’t fret about these matters. Nature has worked out all those details for Us, allowing Rhinos to resolutely fumble forward.
