You break so many things since your birth to your death and with each breaking, there is lots of emotions and feelings attached to it...
In childhood you used to break toys, you laugh on it and if it was your favourite one, then the emotion changes... You grow up a bit then you intend to break whatever comes in your hand, its your destructive age...
In your late teens and early twenties, you break someone's heart, you break relationships, you break things which sometimes you are forced to whereas sometimes you want to...Year passes, but the habit continues in the form of trust, belief, faith, friendship etc...
You aren't actor but still you have to act and pretend things as you want...
As you grow older and older, the habit of breaking is still following you and now its impact is deeper and deeper...
Its human tendency, you can't change it but you have to live with the fact...
