Feeling like a ghost

Well, I'm back on campus, getting ready to defend my thesis in about 2 hrs. Not Dad's campus, mind you, but mine, over 1000 miles from where I now call home. And yet, everything is so much the same, that I keep expecting to see my friends from when I was here 5+ years ago. I don't seem to stand out at all, and I feel rather like a ghost, like Ebenezer Scrooge going back in time with the ghost of Christmas past. Kind of a strange feeling . . . wish me luck on the defense . . . I'll need it.
