Do you all fight with your spouce?

It was meant to be another boring, quiet, peaceful Saturday. But, my husband and I ended up with a minor arguement over a holiday which we have planned.
Then now am thinking, how many couple in the world always fight, argue, quarrel?

All these years, since courting till we got married, we hardly fight. Ya, no doubt about it that we always argue over some minor matters, but come to think of it, we hardly hardly fight.

Fight in a sense that anything we can shout over it. And follow by a cold war things like that....

Has anyone out there come across couple fight and waiting for another one to say sorry??
