Barbara Herrera has been my best friends since childhood. We are all from Chicago, but now I live in San Francisco and Barbara lives in Atlanta. We didn’t see each other very often. I often write to Barbara and tell of her about all the things that is happening at my company. And she often writes to me about my work. There are also other ways we communicate with each other. Sometimes we talk on phone, or send emails to each other. We are really luckily. In this new age of communication, there are so much ways we can keep in touch with each other. We live in different cities, so we’re in touch all the time.
