X-Mess has come early! The Curbed network has elbowed its way through the holiday crowds to find the perfect gift for you, dear readers. And here it is: a new feature. Email a friend! Okay, Ok. This is a re-gift, we admit— we've given you feature before. But it's back again. Just think of it as you would a snuggly sweater brought out of storage for the cold, hard winter. Sweet relief.
