Based on the book, i can think Kien may be a very lively kid. Just like me, when i was a kid, my father not allow me went out and play with the othe kids. However, unlike Kien, i always can find some way to get out the house and play with my friends. unlike Kien, i will not have a very big birthday, but i always have a lot of guests, and i can stay very late in my birthday night.
