I really don't want to swear, but because of the rebellious mentality of adolescence, words about swearing (even swearing) will pop up in my mind. Is this an oath?

It depends on how serious you are about what you say in your heart. Joining is just a moment of making up your mind. If the past is forgotten, it is not an oath. No one knows anyway, go by yourself. It is not good for you to walk into a dead end and stick to your impulsive thoughts, especially for adolescent children, whose cognition is not complete, and it is easy to look at problems one-sidedly and extremely. In the long run, it is not good for physical and mental development. It is suggested that the landlord take it easy and communicate with older or knowledgeable people.
