B. Below is what Josie wrote in her diary.Mon., September 21   I wore a pink blouse and a blue skirt to work.  I just bought the blouse at Mary’s Department Store yesterday.  It started a big sale yesterday and the sale will go for one month.  However, Robin spilled（濺）his coffee at my blouse this morning.  He was talking to a woman who just started to work today and didn’t notice that I was walking to him.  He said that he would take care of it.Tue., September 22   I wore my favorite boots to work today.  I walked so fast that I fell on the ground this afternoon.  Luckily, no one saw it, and I didn’t hurt a lot, either.Wed., September 23   I wore my sneakers to work today because it was a rainy day.  I didn’t want my boots to get wet.  However, I didn’t notice that my sneakers had a small hole, so I went to Mary’s Department Store right after work.  Then I bought a new pair for a song. It was cheaper than I had thought.Thu., September 24   Today is the hottest day of the month.  I wore a red T-shirt and green shorts to work.  I also played badminton with my students in their PE class.  Students were surprised that I played better than they did.Fri., September 25   Today is the last day of the week.  I wore my new sneakers because I was planning to go shopping with Cathy after work.  Moon Festival is around the corner.  I bought some mooncakes for my family and some things for the barbecue this Sunday－the Moon Festival.
