Never yell at each other unless the house is on fire.
If one of you has to win an argument, let it be your mate (the woman heheh).
If you must criticize, do it lovingly.
Never bring up mistakes of the past.
Neglect the whole world rather than each other.
Never go to sleep with an argument unsettled.
At least once every day say a kind or complimentary word to your life partner.
When you have done something wrong, admit it and ask for forgiveness.
Remember it takes two to make a quarrel.
