Last night, while I was doing my homework, an old friend called. I asked Jerry what had happened, but there was nothing to worry about. He's just come back from France. He told me everything about his summer vacation. I listened attentively because I've never been to France and it was really interesting to learn something new. Then we decided to go to the museum to watch a new exhibition. When we came to the museum, we learned that the exhibition would be only tomorrow, so we did not have anything to do. Jerry suggested going to the park. We were walking in the park when we saw some nice souvenirs in the local shop. We bought a lot of funny things for our friends and us! We had a wonderful time!
