Why does Jo get angry very often?

Jo often gets angry because Amy burned her book and told lies (She said she didn't burn Jo's book). I think Amy shouldn't play this tricks with Jo. And she is always very confused too. So, Jo gets angry very often.

Journal Writing(17th November)

In the city, there are some suburban and urban areas. Suburban is a place that is quiet and has good air. There are many trees. People who live in suburban areas are very free, most of them do not need to work. Urban is a place that is noisy, have air pollution, and many people live in. There are some tall buidings, transports and plazas. People who live in urban areas are very, very busy. Most of them need to work all day. I perfer to live in unban areas because I want to go to study or work.
