Strange Weather

Today our school is helding the last workshop of the year. Our school invited Dr. Wen to have a technology speed in our school. The speech is very productive. On the other side, the weather is very strange. It can be raining cats and dogs for 10 minutes and after that it stops, and after 20 minutes again down. I did not know what's wrong today. Driving a scooter is very hard. I am wet and cold. I really want to stay home and relax in this weather. I need to pack everything for my tomorrow's trip.
