It used to be an event. There used to be a huge tree in the center of the island, and everybody would have a gift under the tree, sometimes it was big, sometimes it was small, but it's usually something from home something that you were missing that didn't come with you when you got here.
But now we have the little trees in our apartments, and that's where our gifts are. If they fit. If they don't there will usually be a red ribbon tied to a branch that will lead you out to it.
