But he doesn't say anything more--in part because there's nothing else to say. And in part... well, because he's concentrating. His motor skills and memory are not what they used to be.... one, three, five years ago. It's not like there are consequences if he falls.

But that doesn't mean falling is his plan. He is silent as he climbs, painstakingly placing foot after hand after hand after foot.
