Occasionally, I bump into such kind of a guy, in an English QQ group, who comes out criticizing what those learners posted all sucks. Generally, the criticism is with offensive and aggressive humiliation. When he is incapable of his cynicism in English (usually even he uses English, most of words are just vulgar and disgusting), then he just uses Chinese to show his scorn by saying how stupid, ridiculous, dumb, incompetent and useless those learners are. Such a case is often full of unhappiness with dirty words and indifference. All of a sudden, the group extinguished to silence. Gone with that happy moment.
To be honest, that kind of a guy is really lame. He does not own the humble attitude to study and knowledge. If you observantly investigate his behavior, mostly finding that he has not even offered constructive suggestions and good tips to those who indeed need help. He could have sat aside by saying nothing if he was really thinking highly of his goodness that nobody else can be his rival. While he performs in unctuous tone and just sucks.
What a big deal? Even though those who currently are not so adequate to English, they are on the way trying to learn and improve. That is quite a thing deserved to advocate. Not everyone is good at something in the first place. We were born with unknown idea to get to the bottom of what we hear and see. That is pretty much the reason we keep learning.
We learnt mathematics, literature, ABC at school. Some got As in all their subjects, some were just with moderate scores. There was even a small portion of students who were considered as lame ones because they rarely performed well on studies. Years later, those who got As have high possibility of owning eminent social status, and also those who were not so good at studies before still have chances of becoming successful.
Everyone is unique. We have potential to better life. A butterfly fluctuates wings and stirs turbulence a thousand-mile away. Constant study generates greatness which you might do not notice at present, years later you would understand its significance. Do not go backwards. Do not underestimate your power.
Have a good weekend.
