When Dave was late getting home from school one day Pa was wondering where he was. So, Dave told him in biology class they went to Eif Crabtree’s farm and while they were six boys climbed in a cherry tree to catch a lizard. When they got to the tree it broke and Eif saw it and made each boy pay a dollar but I didn’t have it so Professor Herbert told me I could just stay after school and I would get 25 cents an hour. Pa got all angry and told Dave he was going to go “ talk” with Professor Herbert.
          The next day when Pa goes to talk with Professor Herbert he brings a gun and goes into the room very angry. He starts talking how it is not right that Dave was the only one who had to stay after school and work for him but the other boys didn’t Professor Herbert explained t him that he was working for the school and he came in because he needed to pay the dollar. Pa also gets mad because in high school they were going to look at bugs, lizards, and flowers.  Once Professor Herbert starts explaining that they were there to find germs. Pa goes off about how he doesn’t believe in germs. So Professor Herbert tells him to stay with him and they will look at it through a microscope. Once Pa realizes they are real he starts to like Professor Herbert and learns that he is teaching the right things.  Just like the meaning of cherry tree, you can change. Pa changes by giving the Professor a chance and learning that things are different from before when he went to school. He also learns that his son is getting a good education.
