I would spend the next two years in denial. I made excuses for both my parents over and over again as the memory thieves slowly stole things from right beneath our noses.

Life ain't for the faint of heart. You have to wake up each and every day and realize that you can and will begin again. It doesn't matter if you've screwed up or lost your way or made giant mistakes or failed or fallen, you can always keep going forward.
