Apparently, you have to open your invvetory and click the thing. But my game is bugged and clicking the mirror actually gives me the description for the grass from an earlier quest.hi need help -the moon thingy is the easiest. Talk to Vanessa in library, she gives you a mirror. Use the mirror in the yard at 5 am during a saturday or sunday. can someone tell me exactally where do you use it it says in the court yard which i tried on Sat and then Sun at 5 nothing happens. Thanks
