38. Don't fight
In love, using reason will be counterproductive. It is not good to have a fight between husband and wife in front of children if you want to create a joyful home. Kids learn very quickly what goes on around them. If parents perform well, they will develop well and vice versa.
Fighting in front of them will cause them to adopt similar behaviors outside of the family. If they start showing their negative attitude, sit them down and calmly advise them. Let them learn to deal with conflict in a mature way instead of throwing tantrums.
