The question works the same for all of us, or me. I think. Am I just a figment of your imagination? Or are you a small part of my imagination? Do you not exist, and is it only I that exists? That's a fun question, quite interesting. It would be virtually impossible to answer that we do exist. We feel, touch, see, hear and taste things. If we do this, that happens. Same holds true the other way around. So do we really exist? It's hard to tell, but I certainly hope we do. For if we don't, we don't have much to live for. Or do we?
