My life has simple rules..!
I don't fight with anyone. At least, it won't be started from my side. If someone starts it, the reply will be definitely there. Action always has a reaction, but here it will not be equal, it can be more or even less. Once initiated, it would be on my mood how to react, when to reply; because when it's started that means I've been given the permission to do anything according to my mood, strength, power or style!
But, there are exceptions. If someone is important in my life, I would ignore the actions coming from my special relations. They get chance until 3 times, and after third time, I'm free to react!
