Late for work

So today, I woke up feeling refreshed and ready for work, and surprisingly got everything I needed to get done done earlier than usual.  I was feeling good at my accomplishment, until I noticed that it was an hour later than I thought.  Apparently, I had set my alarm to my summer internship, which started at 10 am, instead of my current internship, which starts at 9 am... and I had just gotten everything done at 8:45 am... and still had an hour to get to work.  *cue facepalm*
