Sometimes in our life we are not able to express the truth to a person due to his behaviour & ignorance and let him do anything he wants. If we tell the truth then he blames us and the small thing turns out into a bigger one. Nowadays, all we can do is bless them and do what we need to do and not thinking of what is right and what is wrong for him. Free advice days are gone. We just have to focus on our actions and do good deeds. Worrying about what others did to you will make you sick and disturbed. Leave everything to God. He is there to look after those.
