Oh yeah? Good thing it's warming up, then. A few weeks ago the only thing I'd have been able to think about on a long walk is how much I couldn't feel my ears.

[From that expression, Shirogane doesn't want to talk about what his long walk is giving him time to think about; Zhao's pretty sure he remembers, if vaguely, a blank place that should have had a lot of other people in it.

Maybe it's better not to bring that up, too. Dreams are personal.]
