These two statements seem contradictory to me...all families are different. DH and I don't really have this type of money disagreement, but several people have said that they do.....It also makes sense that a group of IRL friends have similar reactions. It also makes sense that a bunch of strangers on the internet have very different reactions.
I used that phrase because the other poster did first so we'd have something to agree on. I think an unusually large amount of people on here have said they never have disagreements about money. Sorry, but that just really surprises me. I honestly can't think of ANYTHING my husband and I always agree on. DH and I consider ourselves fortunate that we've never had to fight about money because we have similar enough ideas, but that doesn't mean we don't disagree sometimes!
He thinks "why on earth would she need two crockpots!" I think "haven't you got enough of those tools already?" He thinks I leave the lights on too often, I wonder why he has the fan on when he's not in the room, etc. Little things, but things we talk about because we tend to talk about everything that crosses our minds.
DH and I disagree regularly about lots of things. Even in the things we agree on, there are variances within those things! That certainly doesn't mean we fight, but we do discuss.
