Who am I?

I awoke and remembered nothing. Not even who I was. Next to me I saw an old man, grinning.

He laughed and asked what my last wish was. I moved away afraid of his cruel and menacing smile; his teeth yellow and sharp. He explained that my second wish was to forget everything I knew about myself.

Unsure of what to do but afraid of missing my chance I made my last wish. I asked to know everything about myself.

His smile growing deeper he said “Funny. That’s exactly what your first wish was.”
