Silent twins
Twins Jennifer and June Gibbons were born in 1960 and their main feature was that girls from childhood refused to communicate with people (even with parents). They perfectly understood human speech and even talked among themselves (though this sounded more likely like ordinary babble). When the sisters grew up, they were sent to a madhouse, but soon they were released. A sign of mental illness was not observed. One of the twins, June, spoke only after the death of her sister. She said that so they agreed many years ago: when one of them dies, the second will begin to communicate with other people. The reason for this strange behavior of the sisters still remains an unsolved mystery.
