We all know that men and women are from different planets. That is why, we can't understand the psychology of both of them. However, based on experiences we can easily find out when men are good and when they are cruel. Either to make their women jealous or to take some revenge, men can get cruel at times.
Emotions are s***: Men are not emotional and thus they feel that emotions are nothing but a piece of s***. They are not emotional that doesn't mean that women have to change themselves. Women are emotional and this is not a weakness... Men will not be considered cruel when they start respecting sentiments and don't play with the emotions.
