Sometimes if a person passes all day long criticizing people, it might be because they´re not good with him or herself. In some cases it´s because in their homes is happening a bad situation. Maybe someone of their family died, or their parent divorced, or they don’t have that love that we receive every day… I think maybe this is why they critic all the people that they see daily. It´s the only way that they could get respect and forget about their problems. Also some parents treat their children as they were treated when they were younger. However, the majority of people who were abused as children do not abuse their own children.
You don´t need to criticize others because of things that are kind of dumb. Everyone is how they like to be, if someone has longer hair, wears clothes that are not how you like, is very good at school, wears glasses, is taller, is shorter, or some other things they are OK like that, they like themselves.
Some years ago, I was in my school. I was 7 years old. There was a girl that was always criticizing others. Once, she critic me because I liked a boy. She always told me things like: “you´re awful”, “you will never be with him”, “he is too much for you”, etc. So obviously, I got sad. She did that with all the kids in my class. But the truth was that she had problems in her home. She was living with her mom but not with her dad. Her parents got divorced some time ago. She was so sad with that, the only way that she would forget was by criticizing others. Some time later, she apologized with me and now we are friends!
These people need to think positive in their lives. Maybe not all the things that happen in their lives are negative. Sometimes they need to think that they still have a life, they have friends, they have the rest of their family, and maybe there is one person that wants them to be good and maybe they´re doing everything for them. These people are going to be good
someday, but if they can´t, someone is going to help them. But the best way of getting better in these situations is try your best seeing the good of their lives.
