That really is just the way it is. Most of the time we are 'invisible' to other people. More than once I've gone out with the express purpose of not talking to anyone, and you know what. They don't talk to me. I don't do it any more. It was just to prove a point. Now I talk to anyone, even at the risk of coming across as a bit strange, well stranger haha. I waved across a crowded room,though I wasn't waving but drowning. Nobody noticed me so I put on my coat and left. It was late, too late but then it had always been too late. Too late and I was too far out. And not waving but drowning.
