Dear Mike and Donna,
Wasn't I supposed to babysit Renee today? I've been standing out in the field behind the library for 45 minutes now. Wasn't it 4:30? Or did you say 5:30? Donna hasn't showed up with her before going to her doctor's appointment: Mike hasn't gotten out of class yet.
You didn't just . . . um, drop her off somewhere . . . ? Right?
(The answer to the above train-of-thought was to be found in the email that never arrived, Marquette's and AOL's servers being on questionable terms.)
