At times, you meet people who do wrong to you, and you know that it is absolutely useless to waste your time in trying to make them understand about all that they have done to you.
You must identify people correctly, and know that you cannot change everyone.
There are a few people who will never change themselves even if they have done wrong to you, and this is because they lack the realization about the same.
When you know that someone has done wrong to you, and that person is not ready to accept it or change things for the rest of their life, it is rather better to leave that person as he or she is!
Stay silent as that will make sense for you. You cannot make someone understand if that person does not have an intention to understand.
In that case, you cannot shout the whole day and think that the other person will make improvements in him or her overnight.
In such a scenario, the ideal decision would be to leave that person, and get going! Stay silent and walk in your own path, and accept the fact that you cannot change all people.
