There are times that when we explain ourself to someone, they might misunderstood what we are trying to say. They may see it in a negative way and that leads to misunderstanding. They felt like they have been judged or that they do not know what it is meant. But that is not the case as we are just trying to help that person to understand such things in a more simplified way and not complicate their brains.
Sometimes, it may also be in a positive way that the person we are trying to explain to thank us and appreciate our help to make things easier.
Some people may judge us and some may appreciate the little things that we can do for them. But, most of the time they felt like their ego has been stepped and reject all the explanations that we are trying to do for them. Always remember not all people who we encounter wants to hear our explanations. Sometimes, it is better to be quiet than to speak out what is in your mind.
