I certainly talk with someone... or more like, a voice answered me back if I allow it.
That's where I get my best and most creative ideas and informations from.
It also remembers me of dates, what I thought of earlier, what I might consider doing...
I can make it shut up and then, I do not hear it anymore. But I cannot manipulate it and cannot control it at all. It's the very same 'conversationalist' I had since childhood. (But back then, I didn't answer back.) Very cheeky and meek personality, fits me well. We agree almost always.
It's weird. Oh well, without it I would be even more scatterbrained and distractable. It's very advantageous to have.
The only thing unnerving is, that when it 'talks', it's hard to remember it did. That the idea wasn't mine... or, well, it was, of course... but... gosh, this is complicated.
