When Twins marry
The picture is a group photo of eight people. Four adults, and four children. Two adult women, two adult men, two young girls, and two young boys. It appears, that the two adult men, who are twins, married the two adult women, who are also twins, and their kids, both the two girls, and the two boys are twins too. The twins are all wearing similar outfits with their twin pair to highlight their similarities. The picture was taken outside, there are several trees in the background of the picture.
