Text message: So everyone seems pretty devestated you left 4th period haha
My text reply: Oh I doubt it. I left 4th period last in 1976. You've probably texted a wrong number.
Text message: What?
I'll be sure to update you if my 4th period desertion is really causing repercussions up and down the space time continuum later. (Where 'later' has applicability, of course.)
