[EX Q]: Article: All things change except barbers, the ways of barbers, and the surroundings of barbers. These never change. What one experiences in a barber's shop the first time he enters one is what he always experiences in barbers' shops afterward till the end of his days. I got shaved this morning as usual. A man approached the door from Jones Street as I approached it from Main--a thing that always happens. I hurried up, but it was of no use; he entered the door one little step ahead of me, and I followed in and saw him take the only empty chair, the one headed by the best barber. It always happens so. I sat down, hoping that I might sit in the chair belonging to the better of the remaining two barbers, for he was a bit ahead. I watched the probabilities with strong interest. When I saw that No. 2 was gaining on No. 1, my interest grew to solicitude . When No. 1 was gradually losing the race, my solicitude rose to anxiety. When No. 1 caught up again, and both were about to finish and say "Next!" first, my very breath stood still with the _ . But when I saw that he had lost the race by a single instant, I rose angrily and quitted the shop, to keep from falling into the hands of No. 2; for I have none of that firmness that enables a man to look calmly into the eyes of a waiting barber and tell him he will wait for his fellow-barber's chair. I stayed out fifteen minutes, and then went back, hoping for better luck. Unfortunately, all the chairs were occupied now, and four men sat waiting, silent, and looking bored, as men always do who are waiting their turn in a barber's shop. I sat down and waited. At last my turn came. A voice said "Next!" and I give in to No. 2, of course. It always happens so. I smiled and said that I was in a hurry, and it affected him as strongly as if he had never heard it. He explored my hair with his claws and suggested that it needed trimming . I said I did not want it trimmed. He explored again and said it was pretty long for the present style. I said I had had it cut only a week before. He stopped for a moment, and then asked "who cut it?" I stared at him from the mirror and replied "You did!". Then a dog-fight attracted his attention, and he ran to the window and stayed and watched it...

[EX Q]: Article: Growing up in Puerto Rico, our family was no different from so many others. My parents got married after my father came back when the war ended. Both of my parents were struggling with the hard economic realities of the time. But somehow, they found time to cherish those cultural values that shaped our everyday life. In our daily life, we celebrated together with our friends or family members every birthday, every graduation, and all holidays with music and dancing, typical foods. When we visited our family in the countryside -- a trip that took about two hours in a car, with five children fighting as to who would get a window or the front seat -- we would break into song, and somehow the trip would turn into one full of happiness and fun. We would sing not only interesting children's songs but also beautiful love songs -- songs about the love of the country though we didn't understand the meaning of the words many times. I came to Philadelphia for the first time in 1973 to do a residency in family medicine. I remember the many hours of work. I was facing issues of life and death and suffering the clearly social unfairness and issues of poverty and race. These were all aggravated by my feeling of cultural differences. An important turning point in my life happened one Saturday night when I attended a concert of Puerto Rican singer and composer Antonio Caban Vale. The music showed my familiar rhythms, and the words spoke to my heart. I had found a space to express, celebrate, and share my culture in Philadelphia. Therefore, I believe diversity is seen as an advantage and not as a disadvantage. As a Puerto Rican, I am a mixture of races and I believe in my strength because of this.

[EX Q]: Article: A few months before I was born, my Dad met a stranger who was new to our small town. From the beginning, Dad was fascinated with this enchanting newcomer and soon invited him to live with our family. The stranger was quickly accepted and was around to welcome me into the world a few months later. As I grew up, I never questioned his place in my family. In my young mind, he had a special position. My parents were complementary instructors:Mom taught me the words, and Dad taught me to obey them. But the stranger... He was our storyteller. He would keep us _ for hours on end with adventures, mysteries and comedies . If I wanted to know anything about politics,history or science,he always knew the answers about the past, understood the present and even seemed able to predict the future! He made me laugh, and he made me cry. The stranger never stopped talking, but Dad didn't seem to mind. I now know that my early concepts about relationship were influenced strongly by the stranger. Time after time, he opposed the values of my parents, yet he was seldom blamed...and NEVER asked to leave. More than fifty years have passed since the stranger moved in with our family. He has blended right in but is not nearly as fascinating as he was at first. Still, if you were to walk into my parent's room today, you would still find him sitting over in his corner, waiting for someone to listen to him talk and watch him draw his pictures. His name? We just call him..."TV". He has a younger sister now. We call her "Computer".
