Good point -- especially at a home game that's supposed to be for fun, you don't want to push someone into showing their cards. I've seen it done numerous times at Casino tournaments, though, because players want that information.

What I'll usually do when I've called someone's bet is to not immediately show my hand. I'll ask them what they have, then I'll only show my hand if I've won. Although if they're acting like they were caught bluffing and are waiting to see my cards so they can muck, I'll just show, especially in a home game.
