Il-Jung: Hi, Bo-Sul. Were you in school yesterday? I ~didn\'t see~ you.
Bo-Sul: No, I ~had to~ go to the optician to get a new pair of glasses. I ~have been having~ trouble seeing the blackboard recently. I couldn\'t read what Mr Henderson ~had written~ on the board in math lesson last week. I gave a stupid answer and everybody laughed at me. It was so embarrassing!
