Alistair, 

I don’t have any family that I can remember. None. I went on a blind date last weekend and realized that I do not recall anything from before three years ago. Your significant experience may aid me. What is the most probable explanation?

Newbie, 

You are most likely a highly covert CIA operative who had all his past memories erased to help him carry out his operations with cold and unhesitating callousness. Unfortunately, you seem to have also forgotten what it is that you’re supposed to be doing and have probably been wandering around – a loose human cannon – for the past three years. Now you’re dating; good on you.
