Orbs Float Around the Christmas Tree

Below is a photo from December 18, 2015 showing a green orb floating near a Christmas tree.

Another photo from the same day shows a blue orb that seems to be behind a wire near a Christmas tree (yet another example, like the 45 ones here, of an orb far from the camera that can't be a dust speck near the camera).

This photo from a day earlier seems to show an orb speeding by this Christmas tree.
