B: Oh! My legs are so sore!
G: Really? What did you do during the weekend?
B: I went inline skating with my friends at the park.
G: Did you have fun?
B: Yes, I did. But it was also my first time, so it was really difficult. I was scared that I would fall down. After a short time, my muscles were really tired.
G: Next time will be easier. You just need more practice.
B: What about you? What did you do during the weekend?
G: Actually, I also went inline skating. I go every weekend with my father. We usually skate about 20 kilometers each time.
B: Wow! How can you skate so far? Your muscles must be really strong.
G: I’ve been skating for three years now. You could skate that far, too. You just need to build up your muscles. Let’s go skating together next weekend.
