How To Deal With Toxic People?

Once upon a time my cousin asked me why I am too weak to handle people who play their card with me and leave me. I replied I trust them and don't expect them to play with my stupid innocence. He laughed and said you are really very innocent to this world. Because I don't even trust my own siblings and you trust strangers. U need to be bold to fight back. 

That day I realized that if we do something for good to someone without even asking anything in return it is our good deed, but that same person play card with us, then what to do? I don't expect anything from anyone but after doing good to someone, they forget it and make unnecessary topics and gossip behind your back then what? 

The answer is make yourself so strong, that whatever they do should not affect. Because weak people also stay backstage and try to fly. They can't come in front and tell you anything. Because they know their wings will be cut off if they come in front. So dear readers don't destroy or criticise yourself for being good to others, it's your good deed. And there should always be difference between a coward and a strong person. So, keep doing good and stay happy...
