Goblins are very particular about their hands.
It’s not that hands are sacred. Indeed, Goblins lack such a concept.
But a Goblin’s hands are always busy. They will be clicking or drumming or rubbing loose change or pointing at something. Goblins don’t even like foods that require utensils to eat.
For a Goblin, to sit and hold someone’s hand, rendering their own immobile, is the ultimate sign of intimacy and trust. It is rare. It is special.
That doesn’t, however, stop some of the more enterprising Goblins out there charging people for the right to do so.
