I'd say they lean more on the former side, but only so much because 1) they're all adults, they can all restrain themselves to a certain degree and 2) they all do dumb things that would probably need a shout from one of the other two like "hey, maybe don't"... and honestly if it's a case of someone making w'htal annoyed or mad, they mostly let him do what he wants because their choice, their funeral.

If I had to pick, Urianger definitely the one to be the more indulgent one...... maybe it's his soft spot for small, cute animals and such--
