I have stayed in Princeton for more than one month.  It often rains here, which makes summer not very suffering, compared with Beijing.  Today it rains off and on. In the morning I didn't bring  umbrella to school, although I have one. My room is a little far away from the campus, and I take bicycle to school everyday. Considering it is not convenient and dangerous to ride bike with holding an umbrella at the same time, I left my umbrella in room. Unfortunately, it started raining again when I was going to go back home. Even worse it lasted for 1 hour, and didn't seem to stop , so I had to go home in rain.
