Dear Diary,

    Today has been great. It was my birthday and I got a lot of presents from my friends and family. My favourite was a big green dinosaur. After I opened all my presents, I went to Paul's house. He is my friend. We played football.

    In the evening, my mum came to pick me up and we went to my grandma's house for a birthday meal. After that, we visited my sister in Bandung. It took us 4 hours driving from Jakarta to get there. By the way, now I'm sure that my mom is a good driver. When we arrived there, my sister then made me a yummy chocolate cake. I ate two slices. We spent one night before we went home. It was really fun and exciting.

How did the writer and his mum go to Bandung?
