Today is Holloween, the day before my birthday. Terrible thing is my professor switches the Taxation midterm to my birthday, which means I can't join any Costumes party or Trick-or-Treat activities. Oh! Actually I can, if I dare to get another B- score.>< Anyway, I walked along the Main Quad and Green Street this morning and saw lots of cute people wearing costumes on the road. That's really an interesting view.
