Nah, it was my handwriting, used the same lingo and joke I remember using at the time, took up most of the board... which is why I was so shocked it hadn't been erased.

Most of the time people wrote on it, they were gracious with the space.

Due to typing far more often than writing, and many years later me figuring out oh haha I'm actually naturally left handed, my writing is a fairly uncommon kind of small cap block print, otherwise I am basically the only one capable of reading my non block print scribbles.
