That's just weird - I heard another similar story a few years back...brother and sister, adopted as toddlers, made contact with eachother years later. They then started an incestious relationship even though they knew they were related. Psychologists said that it was a way of dealing with teh emotional bond that had been severed as children. When you get to an adult the sexual bond can replace this. I just find it weird and very sad. I have 2 brothers and .....wow the thought just makes me squirm....
