He means well, just preferring to act as opposed to talk. That isn't to say he doesn't understand what polite conversation is, he just doesn't care for it. Being a fan of being more on the physical side of things, his favourite hobby and sport of choice is wrestling, to the point of having ridden that as his scholarship through school. Sal's long term plans though are to head into massage and physical therapy, dabbling in coaching.
I've decided that because Sal's designed to be a little harder to read, that earning brownie points with him will be a bit harder, functionally being what is a "hard mode" if you're looking to romance the croc.
