Sacred Haven of Debauchery

There are some suspicious guys standing on the common balcony.
Let me start from the beginning.
I get in the elevator to my floor, and when I get out, I see three people standing there... a man (with a clearly criminal past) and two women who also look very suspicious. One of them greeted me and congratulated me on a holiday, but I don't know which one; they said it was February 23rd, but today is February 22nd! And she also asked if I was 18, I answered no (damn, do I look 18? -_-), I opened the door and closed it behind me... I suspect these are "friends" of my neighbor... damn... maybe they'll call... but the camera isn't working so I can't check... no, I'd rather just stay inside...

It seems like they've left...
