I have a friend,lets call my friend here as K. K here has a partner, named L. K said that L always complains about K, calling names and such. They would be arguing about something day in and day out.
My opinion? K here is not an isolated case. People keep on pointing other people's mistake while arguing and though this is not something that is to be proud about, it happens.
When we are in love, we keep on praising and showering our partner with happiness but when we argue, we dig all the skeletons in the closet and throws them right on the face. Why must we point the mistake that was done and act like there were nothing right that happened between the two souls? We open our eyes to the mistakes and simply shut our senses to whatever good deeds that were done before. Learn to forgive and forget.
If you keep on pointing at other people's mistakes and ignore all the good things that were done by them, then that will be your biggest mistake yet.
Peace, no war.
