I don't like to say, "Good-bye". It sounds so final. But so many countries around the world say, "I'll see you again" is their 'good-bye'. This is much nicer for me, in that it just isn't so final. "I'll see you again" in Spanish is "hasta la'ego" (spelling???), in Nepali it is "pheri betoula", in Russian it is "das vadanya", and in Chinese it is "cai jian".
Over the years, I have had to say 'good-bye' to many friends, some I knew that I would never see again. And tonight, I will say 'cai jian' to my friends who I have been traveling with in Cambodia, as they leave Siem Reap early tomorrow morning. Many departures aren't sad, with the knowledge that we plan to meet again.
The hardest ones, however, are when I leave the States and need to say 'see you again' to my family. Sometimes they are a bit frustrating to be with, but then again, they are the hardest to leave. No, I am not homesick right now, just preparing for another departure, and a few days on my own, before I meet up with more friends.
Just a few thoughts, on my nomadic travels in SE Asia... I'm not saying "good-bye", but I will see you again. I will have more stories to share when I get home.
