It's always a roll of the dice when parents have multiple children as they never really know how well the siblings will get along.
And while it's common for parents of identical twins to dress them the same, that reality is just as true for them as we often find that they'll have very different personalities, tastes, and aspirations.
Nonetheless, it's not exactly unheard of for some twins to do everything together and have a lot more in common than ways in which they differ. This was particularly true in the case of one pair who ended up starting families with another set of identical twins.
But if that already seemed like a one-in-a-million case of worlds colliding, just wait until you hear how things turned out for two very close sisters.
