The song "I'm About" by Gilbert O'Sullivan is about a person who feels that someone close to them is avoiding them and keeping something from them. The narrator expresses their disbelief that this person would let them down or leave them, but the recent behavior makes them suspect that something is wrong. They plea for the person to communicate with them and let them know what is going on so that they can work it out together. The lyrics suggest that the narrator has tried to understand the situation multiple times, even examining their own thoughts, but they are unable to find a clear explanation. They fear that they will be trapped in a room filled with sadness and memories, losing their faith in someone they trusted because they are being deceived. Although the narrator knows who is deceiving them, they choose not to reveal their identity. Overall, the song conveys a sense of confusion, hurt, and longing for honesty and open communication in a relationship. The narrator is seeking clarity and resolution, hoping to work through the issues with the person they feel is avoiding them.
