"No one really knows me. People think they know me"

This quote by Johnny Thunders talks to the concept that individuals typically think they know someone, but in truth, they do not. It's a reminder that we can never really know somebody else, no matter how close we might be. It's a reminder that we can never ever truly comprehend somebody else's thoughts and sensations, which we should take care not to make assumptions about someone else's life. It's a suggestion that we ought to be open to finding out more about someone else, which we ought to be willing to listen and comprehend. It's a pointer that we need to take care not to evaluate someone else based on our own limited understanding. Ultimately, this quote is a pointer that we ought to be open to reading more about another person, and that we ought to want to listen and understand.
