Couples do not need to sit down and talk. It usually ruins the relationship. If you want to grow old peacefully and happily with someone, accept them for who they are and hold your tongue. The irritation will pass. It's better than the frustration of getting into a three hour go-nowhere "talk."

(I'm still learning this one, and usually have the most trouble during that time of the month. When I feel the urge to bring stuff up, I check it and remind myself that a lot of it is hormones.)
