Befriend

O.M.G The Tiger Rising is so amazing and the main characters in the chapter I'm reading is Rob and Sistine and Sistine is a new girl with a really fancy dress and is not looking forward to live in Florida. I think Rob and Sistine will befriend with each other and befriend means to become somebodies friend. I think Rob will start it because Sistine does not look like she is the type of making tons of new friends easily and Rob does not have any friends and so he might want to being with Sistine. It looks that their friendship will start with hatred and turns it to frienship but that would take a long time to grow. What do you think will happen?
