But I suddenly wasn't good at having friends. Something from the month before had made me shy. I wasn't very happy about people in general and it showed with these women. I questioned when they were nice to me and bristled when they whispered about anything. I was sure I was just weird to them, some older, freaked-out American who trusted no one.

And my boyfriend had been tricky. Yes, we broke up before I left, but the actual night before I got on the plane, he gave me presents and talked about missing me. So now I missed him.

I went to Rome to look at the Sistine Chapel, and I called him from a pay phone in front of St. Peter's to describe every detail. He screamed things back to me: "What are you doing there without me?" "When are you coming home?" And it rained the whole time and some guy grabbed my butt right there in Vatican City, but I didn't care. I felt filled up with Michelangelo and a boy and bringing worlds together.

But all that rain wasn't good for me. Back in Siena, I woke up the next morning and I couldn't stand up. Being sick is the one thing that can make you feel completely alone; and that was a feeling I didn't need reinforced. When I wasn't up for school, Signora Franci came into my dark, blue room. "Io sento malo," I told her. I felt bad. She immediately started rushing around, yelling at her son to call the doctor. I understood that much, but events were out of my hands. I lay in bed and she brought things to me: a hot water bottle, tea, soup.

I wondered how she could be so concerned, not knowing me, not even knowing my words. But I was so far away from home, I never needed taking care of so badly. I stared at that ceiling, and thought about every friend, every boyfriend, I ever lost too soon. I could see all the people I missed now. The people who hurt me, the people I didn't understand, just drifted away.

Hours later, Signora Franci came in again, this time with green velvet slippers she had bought because I always walked around in socks. She said something I equated as: Of course you're going to get sick if you have cold feet all the time—warm them. "Mille grazie," I said. But a day later, when I was feeling better much sooner than I thought I would, I wanted to thank her more.

It was three weeks into the trip, and she had made me realize why I came to Italy. It wasn't just to see art—though I saw it, and it made me feel creative and part of history and enriched. And it wasn't just to get away. What I needed, and what I never got from sweet Australians or kind teachers, was the returned belief in basic human kindness. Signora Franci didn't take care of me because of anything else but basic human concern: Someone is sick, she's away from her home, make her better. I was 25 years old, I had just started seeing more bad in people than good—and I needed to see that kindness in action.

In my last week in Siena, I just took in the medieval walls, the green narrow hills and the wet, wet air. My Italian class performed a terrible spoken version of "Don Giovanni" for the whole school. I rode to other hill towns on huge buses with my Aussie friends, and the last night we drank wine and wandered through the streets yelling phrase-book expressions at each other.

Days before I went home, I knew I'd be ready for it. There were people to get back to, and I knew who they were. People, in general, could be terrible and wonderful. Sad that I had to go to Italy to realize that. Amazing that I could.
