My buddy swapped his old calipers and now he's way too happy about it.

What good comes from poking fun at someone who's already struggling? the_elizabeth is right, it just kicks them when they're down. Like in League, if a friend keeps losing lanes, joking about it won't help them improve. Or think about a coworker missing sales targets, making jokes just adds pressure. It shows you don't care about their feelings, and can even push people away from trying again. Better to offer support or just stay quiet instead.

What brand was it, and where was the leak exactly? A wrist seal, neck seal, or was it a seam that let go? Knowing the failure point would help others check theirs.
