Oh f***! Yeah, it should be callused. Pandora-Xander isn't callous. Thanks for pointing that out. I don't often get words mixed up. Sorry.

Thanks for your detailed feedback. I totally love it if people quote their favourite line. And I'm glad the optimism shines through without drifting into heavy-handed schmoop. :-D

Thanks again for your eagle-eye, Circe.
