Sheila stayed up very late last night to study for midterm exam, but forgot to set the alarm clock before going to bed. She got up half an hour late. She used only 5 minutes to dress up, then rushed out of the door, and ran as fast as she could to Q65 bus station. What’s worse, the bus made her wait for 20 minutes long, and almost not space for her to get in. It is so bad! It must indicate an unlucky day! After an extremely crowed ride, she got off the bus and transferred to 7 train with a very bad mood. It’s absolutely impossible to arrive on time. On 7 train, she was still thinking of materials that she reviewed last night. She felt tired and sleepy. How nice would be if there was a bed. Unconsciously, she fell asleep. Luckily, she didn’t miss her stop. After a hurry transfer to 6 train, she finally got to 23^rd street. It’s already half an hour late for the class. When she got out of the station, the warm sunshine, the blooming flowers, and the bright green grass shocked her sense of vision unexpectedly. The spring has come. It’s wonderful to smell the spring in the air! The tinges of spring woke her up, poured magical energy into her body, and got rid of her negative mood away. At this time, her good friend, Claire, came across. Claire knew Sheila must has studied for almost a whole night as usual, thus Claire told her not to do that often. Sheila slowed her pace down, still enjoying the spring, and walked into campus with Claire happily.
