It is nice to have something to keep to yourself. In this world, we are sharing every bit of information with everyone in the world (literally) and it kinda takes away from having personal moments. You get a warm feeling when you see something 'magical' happen and you are all alone...or even if its you and a stranger, because to you, they dont exist after that moment you shared. Over time though it begins to seem like a dream and that is usually when I end up telling someone....for fear of losing that feeling; for fear of that moment disappearing.
