Should I be concerned...

that I'm supposed to teach tomorrow afternoon, I'm stuck in Dallas until morning, my syllabus is only about half-finished, and I still haven't heard any official word from Huston-Tillotson about my adjunct appointment? I did get a cryptic email from the guy who interviewed me saying the job is mine and that I should definitely show up for class tomorrow, but somehow I'm not reassured. This is the sketchiest gig ever.
