Thank you very much for your topic.
Last week, one of my colleagues asked me “how can I learn English? All of my attempts lead to failur”. I introduced her Zabanshenas.
She was very happy about it. And she said "I call my colleagues “gray”. I asked “what do u mean by gray?” She said “they have nothing to offer to you. Nothing.” I said: “what do u expect them? They have nothing to offer to themselves.”
On the other hand, we have black people too. They are those who prevent you doing whatever you want. They always criticize you. I think it’s because they want to do what you are doing, but they can’t. They are lazy or comfortable with their situation. They don’t want to leave it and when they saw you doing sth good, they feel jealous.
You should be blind and deaf in front of them.
So, be careful about “gray” & “black” people. If it’s possible, delete them.
