When we had our class, our psychology teacher would take any liquid medicine from a tiny bottle. This touched the whole classes. We thought that he should ask for leave and stayed at home for a rest, so he came to each class on time. Therefore, all of us studied psychology hard than we did any other subject. In the end of that term, we told him that how much we appreciated him. We were so worrying about her health that we asked him what disease he got and what medicine he took. With satisfied smile, he said, “I'm quite all right and it's a bottle of tea.”
