based on something that happened to me. I am Barbie in this strip. I looked at a co-worker who I'd worked with for months, five days a week, and completely blanked on what his name was. I kept looking at him--at his face--throughout the day and wondered to myself just why his name seemed to be nowhere in my head. I don't remember how it eventually came to me, but it did. It was probably something stupid like someone calling him by his name or him answering a phone with his name.
The human brain is annoying like that.
