Respect someone after respecting that person, he will think that you are a fool because you respect everyone. You stayed with him for a long time its been years. That person because he had enough of your respect he start insulting you and talk about the way your family poor and the way you don’t have parents.
If you laugh at those who don’t have parents or come from a poor family, you are just calling a bad luck for yourself. You are just going to make your life difficult. Because you have parents you think you are better than others. You will feel the pain that you thought you won’t feel in your life.
Your parents will die and you will need to be supported by the same person you insulted and laughed at because she didn’t have parents and her family is poor. It will feel like no one loves you but forgetting what you did to someone who gave you respect.
So the advice is don’t think that you are better than others and treat them like they are nothing because of their background, because the same thing that you do to someone is what will happen to you and it will be worse than how you did it.
