Who's right?

Remember. Always, in any situation, there are only two options: 1. Prove yourself. That means to escalate the situation, to take offense, to accuse and ruin relationships, accumulating negative memories and emotions (which come out at the next slightest quarrel: "Do you remember what you did that time? Do you remember what you said back?" and so on). 2. Or simply accept the fact that other people have their own truth. It may actually differ from yours and even may be wrong, but you shouldn't try to correct everyone all the time. However, if you want to build a strong and trusting relationship, then you should try to choose the second option in disputable and stressful situations as often as possible.
