When you're traveling alone the desire to meet someone is like a hunger. Explaining it to someone who has never traveled alone would be like explaining hunger to someone who has never had an empty belly. Like real hunger, it can make you a little loopy in the head and make everything around you sharper and more real. Then when you no longer feel it, you can't even really understand what you felt or why you wanted to eat so terribly badly.

When I got home from my long trip I gobbled up people like a castaway survivor. I think there's a Jack London story where the protagonist makes it through a terribly hungry ordeal and then can't stop eating once he's rescued. I was like that for a while too, until finally I realized I couldn't eat anymore and realized some other things that don't extend so neatly in this far-extended metaphor.

The thing I like most about traveling is how you have to work just to get through the day. You don't know where to shop or how to get to town or which bus leaves when. You don't speak the right language or know the customs or have a favorite restaurant you visit too often. You are engaged in a way you just can't be at home.

I can't say I like that feeling of stomach-empty loneliness but I like that I feel something and I love the rush you always get when the cute girl in class passes a note back.

So it was last night and Marie wrote back. We met up on the porch outside the hostel with a little light left in the 11pm sky. It was cold. I sat at the same table where earlier in the night the British couple celebrating their 20th anniversary asked me to snap a picture as they sipped champagne. They were in a different kind of love.

But I'll settle for Marie and I's kind right now. We're going to take the 5.40pm bus to the 2am ferry. We're going to share some booze and food. We're in love, Marie and I. We're never going to speak after Monday, we're never going to kiss. But I checked my e-mail today and no one made me feel like she did.
