My hands are hard. They are cracked and callused, the skin mostly dry, the knuckles scarred from encounters with saw blades, knife blades, rocks, rough wood. I don't mind; my hands aren't for show, not lap dogs to be petted. They are tools, and if they've become hardened it means they don't hurt when I lift weights or move rocks or shovel dirt, if I catch a splinter it doesn't go deep and I can pluck it out without feeling much.
Rough hands are useful. A callused heart? Maybe not so much.
