Verb conjugation of "interessare" in Italian

Thank you for writting back so quickly. I learned English when I was a kid, because we've always been in England during summer vacation, since my grandma used to live there when she was still alive.
It was the first time that we were on the Italian side of the lakes. It is amazing to see how different things can be on two sides of the border. People dress and behave differently. It was a great experience. I even used words from Lesson 45.
I sent a letter 2 days ago. Did you get it? I see that you like sports. I play tennis. Maybe we can communicate together and write about sports and learn Spanish that way. Waiting for your reply.
