This is not true every-time you can be happy but if you feel sad you can make other sad.
Most important part of a human nature is nature. Bad nature converts their friends from good to bad in some time. Change of a personal nature is not possible, but try to keep calm and listen. If people start to listen more and less talk may change their behavior and reduce some problems from their life.
I am a kind of person who just wants to share own things but never listen other person or if I am listening to someone, I may get hyperactive and start a loud conversation. Which change the complete conversation on fight ground. This is just because I came from a different environment and see things differently before marriage and everything has been changed after marriage. Maybe things take time to understand and adapt a totally new environment. I made so many mistakes to manage my life and made people sad. But as everyone knows that life is short and no one knows how much they live. So I am trying to change myself (Which is quite impossible) and at-least change my facial expression.
I am a music lover person so I will try to sum-up my story in a song every-time. Hope you people love it and understand my condition. Here you go:-
Muskurana Bhi Tujhi Se Seekha Hai
Dil Lagane Ka Tu Hi Tareeka Hai
Aitbaar Bhi Tujhi Se Hota Hai
Aaun Na Hosh Mein Main Kabhi
Baahon Mein Hai Teri Zindagi, Haaye
