Don't hurt anyone
Never cause anyone to sigh. Human sighs are very bad things. Have you deprived someone of everything by lying to them day after day? Crying, gasping and leaving your heart on fire? Did you suffer? Misbehaved with people? The man who trusted you like a blind man gained the trust of the man and broke his trust!
Remember, even if the man does not take revenge on you, every time he sighs at the thought of you, his soul will take a complaint to the Creator. God sees everything.
No matter how much you pretend to be a good person, or how much you float in the ocean of happiness by telling lies to someone, if you hurt someone's heart, you will have to suffer the punishment in this world. The person whom you have kept away from everyone by telling lies day after day, remember that even if he comes and forgives you, even if he does not curse you, you will still have to suffer the punishment.
There is a word for formality. We call it "Revange of Nature". Always be prepared, even if people leave, nature never leaves anyone and it will not be the opposite for you.
