People are different. I am different, too. I like things which they don’t, and so do they. Then it comes to emerge some situations which contradict one party’s interests. And you keep thinking about it!
The more you feed the thought, the bigger it grows, and consequently, the more difficult it will be to forget. Hardly ever has one been able to dump it!
What’s the big deal? Just forgive, and then it will be forgotten! And then, you’re ready to receive the beams of lights which are emitted from God!
