Bond of a Sister and Twin (Video)
There's a special bond between sisters, and if they happen to be twins, well they say the bond is even tighter! Case in point, the Gruenke twins. Claire and Chloe Gruenke were running in the 800 meter race in the Southern Illinois track meet, when Chloe was injured running. Rather than continue the race without her injured sister, Claire put her on the back and carried her the rest of the race. They went over the finish line together.
