If you can't explain it to a six year old, you don't understand it yourself.
Of course, sometimes it's not about the words... it's just about having someone there to listen.
Seven years would be insufficient to make some people acquainted with each other, and seven days are more than enough for others.
Peace cannot be kept by force. It can only be achieved by understanding.

It's ok to understand other people. But it's not enough. Advertence is necessary too. Because it's easy to understand abstract person if you're not a victim but outside observer. Imagine you say to friend who needs your help: "I understand the man who stole from you because he was starved". Or that: "I understand that scumbag who raped you because his wife ran out on him and he wanted to blow off steam". Only most hard-hearted person can say that.
