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

This a tricky one, but not an impossible task. Usually disputes over small issues stem from the inability to adjust with the partner's behaviour or general attitude. This can easily be solved if one maintains cool and is composed during general discussions. If there is something that really irks you about your partner, it's better to be honest and tell them what it is rather than fighting about it. The other thing is to be mindful of your partner's feelings. Sometimes partners are not interested in say, household chores etc. You can tell them that they will be helping you and the house by contributing. There is nothing that you can't make your partner understand.
