A funny Experience: my exchange student program in Sweden!

I'm going to tell you about my Exchange students program. I was in Sweden during the spring semester of 2013. I arrived in middle of Jenuary and I left Sweden in June. I can only say that this experience has been one of the most important of my life and probably the funniest. There in Sweden I met a lot of people coming from all over the world and you could touch with your hands the cultural differences existing across nations. During my period in Sweden, I took the chance for making some trips around Sweden and in other Nordic countries. I think the capital of Sweden, Stockolm, is really beautiful, maybe the best city in the north of Europe with respect to architectures and places to visit. Anyway, I've been in Lapland as well, and it's stunning watching the northern lights up in the sky. Always There in Lapland, I always had the "coldest" experience I ever had. In fact, I bathed in the Nordic ocean - it was the 21th of March! The snow covered the beach and hills all around it. It was very cold. I was freezing, but after all, it was worth of it. I could keep on telling stories about my time spent in Sweden, but I would need much more space and time. That's all people! See you soon.

[Good job.  Remember that the pronoun 'I' is always capitalized.]
