Internal dialogue is part of our everyday life, whether we acknowledge it or not. Many people are looked at as mentally challenged if they walk through the streets talking aloud to themselves, but the fact remains, we talk to ourselves ALL THE TIME. Being able to hold a conversation with oneself isn't a sign of being crazy, but rather a way to remain sane and rationalize situations without going to others for advice.
Maybe I'm a bit crazy, but I love talking to myself. If I'm struggling with an issue, I can go over it in my head and consider both sides of the problem without having to run to another person and have them solve it for me. That's not to say I walk around everyday holding Parliament meetings internally, but I do enjoy the ability to work through matters on my own with an inner debate.
I may be crazy, but at least I'm fully aware of it. That makes me less crazy, right?
