Twins are always interesting. We hear that they have a deeper connection, they can feel each other's pain or difficulties. Most of us have many questions we want to ask twins, some of which could require a higher level of intimacy to be taken well, though. :)
Some of the twin business will be always unknown to those who don't have a twin, but you can still find your doppelgänger and have a little taste of it, no matter where your stranger twin lives!
