I understand perfectly well the struggles you might have with English language proficiency. I do believe that we should never judge anybody's intellectual capacity base on how good they are in a particular language.
For instance, I may be good a bit in English but can I compare well enough with even children in Korean? I guess not.
So my friend @sochul I actually enjoy reading and communicating with you and I must say you are doing very very well with your English language. Have a beautiful day.
