Mr. Hadley was my 6th grade teacher. I was a tall thin girl weighing barely a hundred pounds. I ended up taking a lot of  36 especially from the boys, because of my appearance. I became an extremely  37 young lady.
One day  38 in the 6th grade class was told by Mr. Hadley that we would be  39 to stand up in front of the class and read the  40 that we had completed.
When my turn came, I  41 to stand up in front of all those students and  42 to their tricks. Mr. Hadley came over to me and again  43 me to read my report. I gave it back to him. He walked to the front of the  44 and said, "Yvonne has a very good report here and I think everyone  45 to hear her read it. If I hear anyone making  46 noises or making fun of her in any way, I will let you fail right here and now. Understood?"
Mr. Hadley walked back to me and  47 me the paper, asking me to go to the front of the class. I walked to the front of the class on legs  48 were shaking and I felt a(n)  49 in my chest. Everyone were all quiet, including those boys. I stood there trying to gain  50 .
Mr. Hadley walked over to me putting his arm around me, "You can do it. I have  51 in you!" His words helped calm me. I  52 the report and instead of the kids laughing at me and  53 me, they all stood up and clapped their hands.
From that day on the kids never made fun of me again and some  54 made friends with me. I continued to be quite shy all through school  55 from that day on I knew if I had to stand up in front of class again. I could do it.
