"Well I'm not an old grandmother, now am I?" He snips back at her, mildly enough over the solid wrap of the scarf around his neck and chin as to be non-offensive (possibly). Still it takes him some moments before he figures out how to navigate down off the icy curb - where to jam the end of one crutch and where to brace the other. Once he's managed that much though, he's off: making relatively long strides to make up the distance between them.

He doesn't pause as he gets level with her, instead brushing straight past her and making for the next curb up. "Come on then. Don't drag your feet."
