Bathroom Philosophy

Every Thursday, at school, I have to take a crap because I'm stuck there for almost 11 hours. The bathroom I frequent on those special days is a small, quaint deal that's conveniently out of the way. So, imagine my surprise when I saw grafitti in "my" stall. However, this was no ordinary grafitti. It was (almost) so compelling that I felt I had to throw in my two cents, marking the first time I have ever defaced a public facility...with a black pen. A transcription follows (my contributions are italicized because I'm special):

"Everyday is tomorrows [sic] future."

"No it's not. Everyday is yesterday's future. You are a dumb ass. If you don't like it, EAT A DIC" (pen obviously runs out of ink)

"You're both stupid. Every day is today's future."

"Technically, every day is a part of the future, which is bigger than just yesterday, today, or tomorrow."

"Except that the future can't exist any time but now."

"Yes!!"
