In the other night, I went to K-Mart with my son. I chatted with a checker who came from India, she asked me where I work and she said: I fell your English is not good, How can you communicated with your colleagues? Or your work needs not so many communications? I felt so hurt about it! And it took me several days to recover!
So just read something everyday and get used to native and nature English. That’s why India people more popular and easy adapt here!
