Last week I made a **suggestion** to my cousin Alex, offering to take him to an **amusement** park. He was very excited because it was his **noisy** place. However, from the moment I picked him up, he was very **normal**, which surprised me since his behaviour was **very** different. At one point, while waiting to get on a ride, he disappeared. **Luckily**, I found him an hour later amongst a crowd. Apparently, Alex had seen a famous basketball player and wanted his autograph. He **decided** to come to me immediately but I was so **angry** at him that we left. It was then that I made the **apology** never to take Alex out again.
