We Got Them A Bunkbed why?

When we first moved into our house we bought the girls a full size bed to share because their room wasn't big enough for two. So for 2 years Aubree put up with Addie's OCD of the sheets always having to be straight, Aubree must sleep on her pillow (or else Addie would come bawling into our room at 3am saying Aubree wasn't on her pillow..I am not kidding), Addie's night terrors, and constantly being kick in the face..by Addie.
So when we got their room finished downstairs we bought a bunkbed so they could each have their own bed and it wouldn't take up a lot of space.
Well, as you can see by the above picture that was  a COMPLETE WASTE OF MONEY!!!
So we then decided to take off the top bunk and make 2 double beds side by side (Addie was saying she would get scared so she would make Aubree sleep with her) so then Aubree would be right there...
NOPE! When we go check on them before we go to bed they are still sleeping in the same bed!!!!
