It baffles me when someone is like “you don’t understand or you wont understand”. I get it, maybe we have never been through the same experience, but that does not take away my ability to understand what it means to be hurt, disappointed, or upset. The degree to which we feel the emotion may be different, but its not hard to imagine a difference in severity. no one ever says “you wont understand or you don’t understand” when its something good that has happened to them in their life. when you get married, you don’t refrain from telling your single friends how happy you are being married, simply because they are single. You graduate with a 4.0, most people do not refrain from talking to others about it with a gpa less then a 4.0 because they don’t understand. Emotions are complicated. Being hurt by a spouse and being hurt by a parent differ, but both parties can understand what it means to be hurt.
I find it hard to think that i would refrain from talking to someone on the basis that they have never gone through the same experience. Its like punishing them because they have never had cancer or because they have never had a friend betray them. These are horrible experiences that i would wish on anyone, especially someone who is my friend, just so that they “understand” me. These experiences can be teaching tools to others. Sharing them only with people who have shared the same experience is like teaching Paula Deen how to make a grilled cheese sandwich.
