People in my experience don't like it when I'm quiet; I must make sound in order to avoid being belittled, judged, and bullied in front of people. This makes you believe that they are good people and that I'm a bad person, but in actuality, they are bad people because they demonstrate that they are not loving, empathetic, or understanding; they want to decide that you have to be like them and that it must be their way; if there is something they don't like, like silence or envy, they become mean and condescending toward me. For this reason, it's important to avoid them if you don't feel comfortable around them because you can't be who you are.
Thus, the best thing you can do for yourself is to surround yourself with sweet, loving people. With them, you can be yourself, no matter how quiet scared, and insecure you are. They like people, accept you for who you are, and want the best for you. They are honest and free from evil intentions, so what you experience is what you get. They also have empathy, which is the capacity to understand and empathize with the feelings and situations of others, and understanding, which is the capacity or willingness to understand and accept other people's (different) way of being, needs, values, choices, etc. Finally, they enjoy silence and calmness. For them, it is the most important thing for living beings to be allowed to unfold and be who they are, so that life should be good and not hard and tough to live, but rather a way of life that is straightforward, loving, harmonious, and tranquil as they enjoy it, which is a better and healthier way of life for both people and animals, and where you are permitted to be quiet together.
