history: I tried my best for an exam, I still failed! You know_comma_ that is tough_comma_ but it happens to the best of us. What went wrong? Nothing went wrong_comma_ we just have different lives in different places. I go visit every now and then. But you failed the exam? Did you revise?
current: I did not revise. Sometimes exams are failed and things are not corrected.
next: At least you know for next time eh?
