Okay, I'm not sure if this is supernatural or not, but... it certainly is a strange coincidence, and I'm interested to hear what people on this board think.
At the cemetery near my home, there is a double grave of 2 baby sisters. The first sister died on August 10, 1910, at the age of 2 years. The second sister was born on that same day, August 10, 1910, and died on August 12, 1912. It seems weird to me that they both were born and died at almost exactly the same date, and at the same age. Comments?
