Cup noodles

Since I forgot to prepare the lunchbox yesterday night, I ate cup noodles for lunch today. When I was drinking the soup of the cup noodles, one of my J.1 students asked, 'Why do you drink the soup, Miss Lee? Why do you eat the flavor essence (monosodium glutamate)?' I was astonished because I know that eating cup noodles is unhealthy and it is not good to eat it in front of my students. (I told them not to take food from MacDonald to school for lunch before) I felt embarrassed when I was discovered by this little boy. However, I am an honest teacher and I didn't want to tell lies so I told him, 'It's tasty.'
