If w/ Direct link technology (A Classic Drama)

I'm glad of that, John. I was frightened. I couldn't bear to tamper with the past. You don't know what it is, it's what's gone. But if it really isn't gone at all, if it can be dug up like that, why you don't know what mightn't happen! I don't mind the future, but if the past can come back like that.... O, don't, don't, John. Don't think of it. It isn't canny. There's the children, John.
