Mindless drivel!

My statistics professor is Russian, so before class yesterday I wrote С Рождеством! (Merry Christmas!) on the board.

Apparently she found this amusing enough that she didn't want to erase it. So she spent the class writing around it--which got to be awkward at times because I'd wrote in fairly large letters.

...no moral to the story, except maybe don't write things on chalkboards.
