Actually, the country I come from, and the level of English they teach by Grade 12, most of the students including myself will cruise through most of college level English here. By the time I was done, I had done and memorized at least 3 or four Shakespeare plays and quotes, and in that weird English too, ha-ha! I myself had to be placed in a higher English class just after a week in an ESL class that was recommended by my counselor in college here. That is after I had passed all the testing. He said just because I was a non -native speaker...wtf. Anyway, that was some years ago.
The point I am trying to make is I am no stranger to the English language. I have been speaking, reading, and writing in English since I started the very first day of school.
To give you an idea of how seriously English language is taken in my country -for any grade 1-12 or in University, if you do not get a minimum of 50% in the final / exit exams ( mind you these are tests prepared by the NZ and Australian and British education departments – All three English speaking countries) , you will have to REPEAT the whole school year.
I myself scored one of the highest scores in English in my final year, and that was highest in the country, and I have papers to prove it.
Everyone in my country does speak English daily so speaking, reading and writing is not an issue here.
As I stated earlier, if I need to address someone, I do so in English if they are in a business place. If I am outside in a parking lot talking to my friends who are of the same culture, then of course I will speak my language......I don't have to speak English just because I am in America...and the trees and insects and birds may not understand me...
I was not addressing that lady, nor were any of my comments directed towards her; she just butted into our conversation....
Whew ....I wrote a lot too...
