My dear friend Allia walked up to me and asked me what her birthday was.
"You forgot your own birthday?" I questioned her, with a puzzled look on my face.
"No," she said, "I mean I want you to remember it. You don't remember anything!"
"At least give me a hint," I pleaded.
Eventually she gave in. "First week of November."
Now, she and I are masters at logic. I myself knew it near instantly. Do you know what it is?
