The relationship between two siblings is undeniable. Sure, your brother or sister tends to get on your last nerve from time to time, but at the end of the day the pair of you are blood relatives, and you’ll always have that (and hopefully a fruitful relationship) keeping you together.
But can you imagine the bond between twins? It is arguably ten times stronger than that of regular siblings. In fact, it seems as though twins can communicate to each other before they’ve even learned how to talk! They’ve even got a name for the secret language—cryptophasia! This usually comes about due to the copious amount of time that twins tend to spend together, as well as the fact that they go through the same developmental stages at the same time.
