Spanish friends

I recently joined the University of Sevilla's Intercambio Lingüístico program, in which you practice the language you are studying (in my case, Spanish) with a native speaker who wants to learn your native language. I had my first intercambio with a girl named Saray. She's a bit older than me, but she's extremely nice and really chill. She dressed quite casually, which surprised me at first, since most of the women here dress well. She is currently studying architecture, so she taught me a lot of history about the city. She took me to the Reales Atarazanas, or the historic Royal Shipyards. It's located right in the center of the city, yet I had never even passed by it before. Saray told me that we could out for tapas sometime (Score! Believe it or not, I still haven't tried the tapas here). She even introduced me to her friends, and told me that I could go out with her and her friends sometime. I didn't expect to see this type of hospitality from Spaniards, since I thought intercambios, at most, only created superficial relationships. But I could see that she was genuinely interested in getting to know people, which I appreciated. Later that night, she sent me a text message, inviting me to hang out with her friends, and that I could bring anybody. At first, I felt like turning down the offer, because I had been out all day and thought I should do something productive (you know, like homework). But Andrea, my roommate, was begging me to go, saying that it's been her dream to go out with some Spaniards. I ultimately agreed to it. We went to a few bars, just talking to Saray and her friends. Most of them know English too, so it was fun to have bilingual conversations. One of the guys is from Valencia, and said that he would cook a paella for us (Score again!). Andrea and I left around 3:00 am, which is still a bit early for them. But I'm happy that I did decide to go out and challenge my social skills.
