Hi guys, let me introuduce myself.I'm Anh and i'm 10 years old.Yesterday, my mom and my dad took me to the zoo. This is my dream! I explore the zoo with my parents, saw many any animals, but i guess the bunny is my favorite :D. The bunny is super fluffy like a cotton candy! In the end, my mom get me some chocolates and a pinwheel. I will never forget this trip.Never ever!
