McGonagall chuckled a little.  "Well, you took that better than I expected.  Besides the communal space, there are a few other changes.  First, you’ll notice on your schedules in the morning, and perhaps guessed from your supplies lists, that you  all  are in a Muggle Studies class.  That was a decision that the Board of Governors made.  It’ll take place in your common room on Monday afternoons for an hour and a half.  Additionally, you will have more freedoms to move about the castle.  You’re all adults according to the Ministry and as such we are electing to eliminate curfew for you.  Please do not abuse this privilege or I will be forced to reconsider."  She glared a little at the high five Dean and Seamus exchanged.
