 Which isn't a feeling that the older man expects of the younger man?
There is one fact no sane man can quarrel with ... But some men aren't sane; thus it isn't always so! I'm not your father's ghost, even if I do look a bit like him. You will, you know, so why quibble about it? At least, you always have ... or do ... or will. We don't have the right attitude toward tenses for a situation like this. And don't look at the machine out there too long—until you get used to it, you'll find it's hard on the eyes, trying to follow where the vanes go.

You are completely outside of time and space, as best you can guess how things are. Doesn't hurt, and when you pull your arm back, you're still sound and uninjured. Then it comes to you slowly that you're actually traveling in time. Then you feel silly, because you'll remember that I said you'd ask that. Well, I asked it after I was told, then I came back and told it to you, and I still can't help answering when you speak.
