London

So, I have an 19 hour layover in London. Most of it was overnight (3pm to 10am). I still have about 4 hours left of the layover, then I'm on my way to Frankfurt and then finally back to Philadelphia. It's nearly a 40 hour trip, rather tiring.
Yesterday I spent the evening in London walking around. It was lovely. I saw Buckingham palace, parliament and a few other sites. Then I just walked around a whole bunch and enjoyed having some time to myself. Needless to say that I've had quite a lot of time to think yesterday and today, it's been good - but hard.
I am having a real difficulty seperating myself from Ethiopia. I don't want to admit that the trip is over, I'd much rather believe that this is just a dream and that tomorrow I will wake up and still be in Frew's house. His family was so wonderful to me, they said that they feel as if I am not just a friend, not just a guest from America but rather a part of their family. I feel the same way. It was extremely difficult to say goodbye to them, especially Frew. He was the only one who came to the airport (we had to be there at 5am) and when the time came to say goodbye we were both crying. After I checked in I had about 20 minutes before I needed to go through immigration and board. We sat at a cafe in the airport and hardly spoke a word. Neither of us knew what to say, we were both about to be seperated from one of our best friends for an indefinite period of time...that was about all we could say to each other. What else can be said in a time like that. He started crying as we were sitting at the table, saying "this is too difficult". I had no words to reply. When I left we embraced and I had to walk away, the tears were streaming down my face and it was the hardest walk I've ever had to take.
It took every rational ounce in my body to not turn around and leave the airport with him. All of me was saying "just stay, don't go back home, you're needed here, your friends are here...just stay". Even as I was waiting to pass through the security checkpoint to get into the gate I was looking out the window at what would be my last glimpse of Addis and I was still fighting the urge to stay. Part of me wishes I had, part of me is still saying that it is more important to be in Ethiopia than to finish my studies...I know some will disagree with this, but these are the thoughts I am dealing with.
The trip was so much better than I could have imagined, it was simply wonderful. It was life changing and I don't think I will ever be the same again.
Is it too much to hope that I'll go back soon? Will it take a miracle for this to happen? If I've learned anything on the trip, it's that miracles are more than possible. I can only hope that the time between now and my next trip is short...or at least will feel short. I've left dear friends and family in Ethiopia and I'd like to be able to see them again in the near future.
