Nothing. I'll let karma do its work on them. If I do something, it will just drain lots of my energy. But, I'm a quite observant person and I connect the dots in silence. It's a bullet to my heart but you've disrespected me the moment you lied to me. You're totally wrong if you think I don't have any idea about it because I always find the truth whether it's accidentally or not. Just don't blame if I turn to be cold and dry toward you and don't blame me if I decide to turn my back on you without any warning someday.
