An algorithm, drawn by a 68-year-old female retired writer in the US.

Yes, how an algorithm works. Okay. I have no idea what an algorithm is. [laughing] Okay. So your drawing a bunch of X. Is that what they are? And zeroes. And Os. [laughing] Okay, or Os. Yes. Actually, it's just hugs and kisses. Okay. You're drawing a bunch of hugs and kisses, or kisses and hugs to me. Is that it? That's it. Okay, thank you. You're welcome. So where have you heard the term algorithm before? Oh gosh. Do you have any idea? Like clearly you've heard it, so I'm just wondering how that would have come up. I don't know. Years ago, we had a Harvard professor here and maybe [husband] seemed to understand what his specialty was, his specialization and I don't know that I did. He wanted napkins that all said X or O on them, and [husband] did. But frankly, I don't know what it is. Okay.
