You are just never there. Your parents love you, think about you, spend sleepless nights while you don't turn up, spend their time with strangers talking about you, admiring you on pictures. But you are not there. All they want is a minute of your time and to know, to be sure, you are happy. Cause that makes them happy too.
Maybe it's one of life's cruel jokes, those who give you everything, don't get it back. You will realize it all when you become a parent.
