Everyone around you seems intent on having a good time.
Of
course, this normally wouldn't bother you, but you have a big
deadline looming in the near future. If you stay where you are,
you fight a losing battle by trying to conduct business as usual.
Try to move your temporary office to the local library or at least
a room where you can close and lock the door. If there's any blame to be
shifted, at least you have a good alibi.
