It's really hard to answer the question who am I because even yourself can't explain the real you. We can define our likes and dislikes, our emotions and what we want to be in the future but we are not sure it'll be happen the way we want it to be now because we don't know what will happen in the future and we can't say that we can stick to our likes and dislikes now and we can't stick to what is our emotions now. For me, the world change everyday so are we, that is why it's really hard to answer who am i and who are you. The people close to us can define us by observing us physically and emotionally but in reality they don't know the real you because there are pretentious people and there are people that's hard to define.
