A blue day Yesterday was really hard for me. I took an exam in the morning,which I don't know if I can pass or not. It was really hard and the puzzles were not typical. To tell the truth, I hadn't thought that it could be that difficult. Then in the evening, I booked plane tickets for me and my friends. But I hadn't realized the departure time was wrong until I paid. Oh my god! What a disaster! I had to pay an extra of 204RMB per person to change flight. Because it was I who made the mistake, I couldn't ask my friends to pay for it. I was really guilty and regretful as my dad had to pay for my carelessness. :(
