The List

Last night I laid in bed waiting for the last of the stragglers to turn in.
Thoughts of what I needed to accomplish for Monday went filing through my brain like a parade, so I thought I'd better write them down:
-pay bills
-return tux
-report visiting teaching
-chlorinate the pool
etc.
I left the list on the floor next to my bed, and stray thoughts kept coming.
When teenage boy came to say good-night, I asked him to add to the list.

Me: Would you please grab that pen and add something to my list?

TB: Sure.

Me: Somewhere around "return tux" would you write in big letters O B?

TB: (As he's writing) O. B. Why am I writing this?

Me: I need to make an appointment that I canceled last month.

TB: What does OB stand for?

Me: Organizational Behavior.
