All settled at orientation

I would say the flight here was the best flight experience I've ever had. The seats had ample room, the service was awesome, and the movie selection was great. Too bad I didn't sleep at all. The woman sitting next to me kept spreading into my seat, more so when she went to sleep. While awake, she would get me to take off my headphone every 30-45 minutes to tell me how bored she was. She talked to me so much that the stewardesses thought we were travelling together. Regardless, Seoul looks pretty cool. It hasn't yet hit me that I'm in Korea and won't be back for a year. What was I thinking?
