I think except my parents, everyone is the same, taking part in accidental amusement and wearing a mask. Don't trust anyone. Is this normal?

Normal means that you have grown up, and the relationship between people is basically the exchange of resources. What value do you have and what benefits can you bring to others? People who are willing to get along with you are those who can give them what they want. For example, you can be a good listener, you are a strong person, you are gentle with others, and you can talk. It cannot be said that all relationships are accidental. You've been wearing a mask. You want to gain affection, friendship or love. You have to give your heart to get the heart of others.

Trust is still necessary. You can't help trusting anyone. You have to believe that there are people who are kind to you in this world, except parents, but they are not easy to meet.
