Because I wasn't aware the last time. So I'm coming in with proof (from other people) that I am not always myself, and there are more of me. But I don't have any concrete proof beyond what I read here, what I've read in books, as to how it *feels*.

I may never get co-consciousness. I don't know if I can develop common knowledge pools. I'll try the leaving notes idea, though I'm sure I'll feel sheepish until and unless I get one back. :)
