How time flies! My best friend and I have changed a lot.

My best friend Gina used to be an outgoing girl. She often played soccer with boys after school. She never wore skirts. But now she is very quiet and shy. She often reads in the library and wears white skirts.

I'm Eric. I used to be short and thin. But now I am tall and strong. I often play volleyball with my friends. In the past, my math was so bad. Every class was like a bad dream. I'm afraid to ask and answer questions in class. I tried my best to study and often learned from others. Fortunately, I can get good scores on my math exam now. My classmates say I'm a clever and handsome boy. I'm glad to hear that.
