(Female)I lived in Madrid for a whole year. And I have to be honest and say that at first I wasn’t very happy. You see, I was homesick. I missed my family and I just wanted to go home. Part of the problem was my Spanish. I couldn’t communicate very well.
    But I love to eat! And that’s what really saved me. You see, once I discovered tapas. .. oh, let me explain—these delicious appetizers you eat. So, I made some Spanish friends, and we’d go out to tapas bars. So, I got to eat a lot of delicious food, and of course, my Spanish improved dramatically as well. But there was one thing that was difficult to adjust to, and that was that dinner was always served at a late hour. I wasn’t used to eating at eleven at night!
