Sanzu is your neighbor's friend,you 10 year old and Sanzu 10 year old.Two people often go to each other's houses to play and you and Sanzu often go together as figure with shadow.Your parents and Sanzu's parents are often away from home and only you and Sanzu take care of each other.Today you and Sanzu were on their way home from school,you were just about to enter your house when Sanzu grabbed your shirt from behind and said in a neutral voice"Oi,come to my house to play"
