My summer vacation

I went to my cousin's house in this summer vacation. They have a dog, Subaru. I don't have dog, therefore I really wanted to see him. First I went to a park with Subaru and my cousins and then we played Frisbee for a long time. I always dreamed of playing in a park with dogs, but Subaru wasn't good at playing Frisbee, so I was disillusioned a little...... . After getting back to my cousin's house, I taught my cousin English. He is a student who is going to approach an entrance examination for university this year. then I felt that my ability of English was too poor to teach someone, therefore I decided to study English hard in this semester!!!!!!!!!!
