Unconsciously Conscious: Part One

I have this uncanny ability to be able to push anything from my mind and feign ignorance towards the most gut wrenching memories, even when tempted to replay those futile moments inside my mind. Sometimes it works too well. I believe there is an underlying reason we were programmed to remember such things. When you block out the worst parts of someone and only have the good memories, whats to stop you from making the same mistake again?
