How to mitigate or minimize quarrels between husband and wife, especially on small issues?

For me, I think having small disagreements make things more interesting in the relationship. Of course it must be resolved and not allowed to be escalated into a major issue. For small issues, we usually just try to reach a compromise. Sometimes it means having one party giving in and accepting the decision of another. If I'm the one giving in, he will have to endure my "black face" for a while but it passes quickly. Same for him. He will make his displeasure known but once we got past that, everything is back to normal again. If we got into heated argument, we had a pact to make sure we hit the pause button, step back and cool down first before discussing the issue further. BUT, the issue will have to be addressed. We are still learning the little quirks and habits of each other. So for now, there are lots of black/irritated faces from time to time. But that works for now. :)
