Now that I am older, my life is different from when I was in primary school. For example, my primary school was near my home, so I used to walk to school with my parents. Now my junior high school is farther from home. I take a bus every day with my friends.

My home has changed too. My family used to live in a small flat, but now we have moved to a much larger one. My grandma lives with us now as well. She has her own room and her own TV set. I am glad that I get to see her every day.

The way I study is also different. I have become more confident in my studies and often attend group discussions. I enjoy studying with my friends. It's amazing how much we have achieved together.

My life has changed in many ways, but one thing has stayed the same: the feeling of love and happiness shared by my family.
