Today's Online lesson I'm a member of two online schools. I usually take 2 classes a day. One is in the morning, the other is in the evening. I have been taking online lessons for more than two years on company A. And, I just started taking classes on company B. I took a lesson on company B today and teacher was Serbian. Surprisingly, his roommate is working on company A for two years. And he taught me the name of his roommate and I know him! I've taken his class three time or so. It was surprising! What a small world!
