The Day-Ruiner (he ruins days)

So I was having an okay day at work.  Things were busy, but not overly so.  Then the Day-Ruiner called.  This guy has been avoiding me for two weeks (it could have just been phone tag, but he admitted it!), and then when he finally called, he was a total jerk.  He half-heartedly apologized for giving me a hard time, but then he kept right on doing it.  Seriously, I’m all tense about it now.
