One of my favorite teacher's was Mr. Angel Quinones.  He was very serious in his class but had a good sense of humor.  You wanted to be in his class and learn because he knew what he was talking about.  He sure knew about hiistory!  When he sat on his desk or stood in front of the classroom and started talking I definitely used my imagination and went back to the Island of Puerto Rico, Cuba or any place he mentioned.  By his knowledge in history and the respect he had for his students made him one of the best teachers at Clemente High School.
