This is my first diary here in English Aloud.  Today, there were 6 participants in my classroom, who came from a shipping company in Singapore.  They are very kind, but have a lot of questions about the marine diesel engine.  All of the questions are always welcomed; however, I should manage the time for answers.  Consequently, I could not finish the lecture today and it has to be continued tomorrow.  It will interrupt the next lectures, so my schedule will be late. To avoid the situation, I have to give them short and clear answers for easy understanding.  I feel so sad because I have to go to the company tomorrow even though it is a national holiday for Korea.  It is not a holiday for foreign participants.
