    John and Ann are from Dublin, Ireland. They've been friends since they were children. They lived in the same neighborhood when they were young and they went to the same university.

    Today John is a 34-year-old engineer. He works in the heart of Dublin. He is very busy and doesn't have much free time. He found a maid (女佣) to clean his house on Saturdays, but during the week he has to make the bed and tidy up his room. He must also wash the dishes. Sometimes he cooks a meal, but most of the time he stops at a restaurant near his home and buys a meal for dinner. He often arrives home very late. Luckily, his maid is quite professional and takes good care of the house. In just 6 hours, the house begins to shine, with a fresh look and clean air to breathe.

    Ann is 35 years old. She lives in a small village in Dublin. She works as a doctor at the village's health center. She starts working at 9 a.m. and finishes at 4 p.m. There is a half-hour lunch break at 12:30 p.m. After work, Ann has to pick up her two daughters from school. After they arrive home, the children do their homework while Ann prepares dinner. Her husband (丈夫) usually does part of the chores when he gets home. First he prepares the children's bath and then he washes clothes. Before dinner, he hangs up the clothes and then the children help him to lay the table (摆好餐具) and ... it's dinner time! After dinner, Ann's husband usually does the dishes while she tidies up the kitchen. When there is too much rubbish, she takes it out.

     When Regina Spektor moved to the Bronx from Russia as a young child of 9, she could speak no English and her family was so poor that they could afford nothing. Yet she carried with her a love of the piano and music.

     "For me, the thing that I loved the most was playing the piano, so when we left Russia I was so afraid I would forget how to play and I would just find a little table and play my pieces," she told "When you spend your life doing something like playing the piano and then you take that away, it's so surreal."(离奇的)

     Her father, Ilya Spektor, said that, little by little, the family saved enough money to afford their first apartment.

     "I was a photographer and, in six weeks, I found my first job in a big photo lab in Manhattan," he said. On the subway one day, Ilya Spektor spotted a man carrying a violin case. The man also seemed to have an Eastern European accent. A conversation led to a visit and, eventually, Regina Spektor was introduced to Sonia Vargas, a piano teacher. She was a well-known professor who taught piano, took Spektor under her wing and trained her for years, at no cost. "I remember talking to Sonia," Spektor said. "She said that when a student is ready, a teacher appears. So she said that I must have been ready to study piano, and so that's why she came into my life."

     "Immediately, how she played," Vargas said. "You can tell the sound. The sound tell you whether the person loves the instrument, loves the music."

     Much later, while playing her own music and selling a CD that she'd created, Regina Spektor caught the attention of a music producer. The rest is history, complete with concerts around the world and performance in front of the Obamas at the White House.

     Regina Spektor greatly appreciated her parents, piano teachers and friends for helping her become the musician she is. “I love the idea that if you’re walking toward the world, the world will take some steps towards you,” she said.
