Today I lived in the margins of The Book of Life.

Not a main character or even side character,

but an absent minded professor's afterthought

scribbled in the edge, rarely read and often askewd-

Maybe a reference to a highlighted word or

some false interpretation of author meaning-

Something a drunk college student may reppeat

or purport as their own thought but not fleshed out,

clearly an imposter, plagiarism. Something that is

circled in grading with the note,

"If  you want to go this direction,

You need to fully explore."

So like a hanging preposition it's dropped, 

doesn't make cut to final draft, that's what today was.
