I swear that even without the formality of a ceremony, these two are married in spirit.

We and Sadie's parents (and any other neighbor who's ever been around these two) often joke that they fight like a married couple.

While camping they argued over whose backyard we were in . They argue over who gets the lego jet pack. They argue over whether Mabel is a
baby sister or a
little sister. It's awesome.
Speaking of awesome...check out this hair.
Fancy!
