Waiting for Departure!

I've been at DTW for about two hours now. I got my boarding pass, my luggage checked, got through security with no problems and got to see my sister off to Washington D.C. It's about an hour before my flight is supposed to board and I'm starting to get a tad anxious. The gate keeper (receptionist at the gate, not sure the official name but this works) told me it's looking good for me to get on this flight. They just made an announcement that the flight from Tokyo is in and that they are releasing them and cleaning the plane and it should be ready for boarding around 4 but for now I'm just going to sit at the gate and pour over my notes and small Japanese language book to prepare myself as much as possible for arrival.
