Love, success, happiness, family and freedom—how important are these values to you Here is one interview which explores the fundamental questions in life.

Question: Could you introduce yourself first

Answer: My name is Misbah, 27 years old. I was born in a war-torn area. Right now I’m a web designer.

Q: What are your great memories

A: My parents used to take us to hunt birds, climb trees, and play in the fields. For me it was like a holiday because we were going to have fun all day long. Those are my great memories.

Q: Does your childhood mean a lot to you

A: Yes. As life was very" hard, I used to work to help bring money in for the family. I spent my childhood working, with responsibilities beyond my age. However, it taught me to deal with problems all alone. I learnt to be independent.

Q: What changes would you like to make in your life

A : If I could change something in my life, I’ d change it so that my childhood could have taken place in another area. I would have loved to live with my family in freedom. Who cares whether we have much money, or whether we have a beautiful house It doesn’t matter as long as I can live with my family and we are safe.

Q: How do you get along with your parents

A : My parents supported me until I came of age. I want to give back what I’ ve got. That’ s our way. But I am working in another city. My only contact with my parents now is through the phone, but I hate using it. It filters(过滤) out your emotion and leaves your voice only. My deepest feelings should be passed through sight, hearing and touch.

B. By calling them sometimes.

C. By paying weekly visits.
