...
So, let me get this straight.
You ditched work to hang out with someone.
I'm now curious as to the circumstances that necessitated this. Was the person someone you haven't seen in a long time? Was there an event you were going to that was only occurring that particular day? Was there no other way to spend time with this person, as this was their last day before they were deployed or something?
I bolded the correct parts.
It was their last day of leave they were available.
But you know what? Its fine.
I don't care. They decided not to tell me this back in August when it happened and waited till AFTER I came back from a vacation to break the news. They clearly didn't care either.
I'm going to look for a new job, and if nothing comes of that, well that's just fine. I'll make the problem go away in one way or another.
