I've always been just awful at Math.
So awful, in fact, that I'd really struggle to stay awake in class.
It was really terrible because my Math teachers were always such nice people and I KNEW they could see me bleary-eyed and all but slumped over and snoring at my desk.
My Math binder was the easiest to pick out because the entire thing was covered in scrawly, black, wordless mental meanderings.
Who knew it'd come in handy one day : )
