Okay, I know its 'real' in the sense of how it functions, but do you ever reflect how strange it is that we do all this work, make all these exchanges, do all this saving of something that doesn't actually exist? People I've mentioned this to IRL don't seem to share this feeling that its actually a very strange system - maybe I'm not explaining myself very well. But the money in my bank account, for example. Its just a number. I go to work in order to make the number go up, and almost everything else I do makes it go down. If someone went into the system and added a few zeros to it, my life would change beyond recognition...yet it doesn't actually exist? What is it?
