In my (many) years as a journalist, I often had to interview couple celebrating big anniversaries, such as Golden or Diamond weddings, and from time to time, you would get a couple who claimed that they'd never had a cross word. I'd always think 'well, either you're lying - or one of you is a complete doormat'. I agree with Galaxy on this - it can't be healthy to never have argued or disagreed to some extent.
Just what was going to say, that if they never had a cross word or disagreement then one of them must be a first!
Yes, we have disagreements. DH still can't get out of the habit of managing and I do not like to be managed. Mostly I just ignore it but not always.
I never, ever heard my parents swear or argue much although my father would occasionally slam the back door, muttering 'Damn and blast!!' and go out to his greenhouse. My mother would then mutter under her breath about him.
