Smile helplessly, stare at the mobile phone for a while, and feel sensitive to boredom, there are only a few people and nurses in the infusion room, upstairs and downstairs are quiet, it is dark outside the window,electronic board for classroom, the bald branches of several sycamore trees are particularly clear and lonely against the background of the night neon. I suddenly felt extremely sad, as if I had been abandoned by everyone. The city outside my house was so bustling, but my heart was as empty as a wild mountain. I am in a panic, and now there is a kind of unspeakable sadness in my heart, which is like returning to the nightmare of the past, lingering. Gently put your head on the back of the chair, close your eyes, and pretend that you can't wake up. Suddenly, a familiar gentle voice sounded in my ear,interactive whiteboards in the classroom, "Jiang Zhishui, what's wrong with you?" Opening my eyes, a pair of smiling and warm eyes like the winter sun fell in sight, I hurriedly propped myself up, "Tang Junran, why are you here?" He conveniently picked up my medical record, "I came to the nurse's station to get the instructions for the new drug. Hey, you have pericoronitis, and your mouth is limited. It's so serious. Open your mouth and show me." I smiled bitterly, and my voice could not help acting like a spoiled child. "Dr. Tang, you didn't see the diagnosis of the medical record, and you couldn't open your mouth." He smiled and looked at my infusion bottle carefully. "It looks very serious. Why did you just come? It's less than half of the time." "I didn't expect it to be that serious." I grumbled discontentedly, "I didn't expect to have a fever even if I had a toothache. It's too unreasonable." "That's because you have inflammation." He sat beside me, his hands crossed habitually, "Where is your boyfriend? Why didn't he accompany you to see a doctor?" I burst out laughing. "I don't have a boyfriend. That's my cousin." There was a kind of unconscious embarrassment on his face. Instead of looking at me, he stared at the infusion bottle for a while. "At least there is more than an hour. Do you feel bored? Do you want to watch a movie?" I pointed to the TV in the infusion room and asked tentatively, "This?" "No, interactive panel board ,touch screen interactive whiteboard, what's there to see?" He opened his carry-on bag and took out a small laptop. "What do you want to see? You can choose." I teased him and said with a half-smile, "Dr. Tang, you still take your notebook with you when you go to work. Is it difficult to watch movies and chat on QQ secretly?" He smiled faintly, "the notebook was broken today, and it was brought to my classmates to repair, so it happened to be around."  I go to work these days. If you have no one to accompany you, I will accompany you after work." I really do not know what expression, or how to answer, his words can easily confuse my heart, eyes are mostly uncertain and evasive, of course, my embarrassment finally can not hide under his gentle eyes, had to pick up the bag in a hurry, "I'm all right, let's go, it's getting late." The nurse sister at the nurse's station smiled at us cunningly, but no one understood my inner turmoil. He did not speak, his lips were still smiling,smart board interactive whiteboard, the wind was light and the clouds were light, without any trace. I went to eat porridge with him. I had a fever and had a bad appetite. I only picked the dishes with heavy taste. After eating half a bowl, I felt that I had no appetite. Tang Junran did not eat much. I knew that he always preferred meat and seldom ate vegetarian food. hsdsmartboard.com
