By the way, do you mind if I ask you a personal question? No not at all. Well, forgive me...

HAL: By the way, do you mind if I ask you a personal question? Dave Bowman: No not at all. HAL: Well, forgive me for being so inquisitive but during the past few weeks I've wondered whether you might have some second thoughts about the mission. Dave Bowman: How do you mean? HAL: Well, it's rather difficult to define. Perhaps I'm just projecting my own concern about it.I know I've never completely freed myself from the suspicion that there are some extremely odd things about this mission. I'm sure you agree there's some truth in what I say. Dave Bowman: Well, I don't know, that's a rather difficult question to answer. HAL: You don't mind talking about it, do you Dave? Dave Bowman: No, not at all. HAL: Well, certainly no one could have been unaware of the very strange stories floating around before we left. Rumors about something being dug up on the Moon. I never gave these stories much credence, but particularly in view of some of other things that have happened, I find them difficult to put out of my mind. For instance, the way all our preparations were kept under such tight security. And the melodramatic touch of putting Drs. Hunter, Kimball and Kaminsky aboard already in hibernation, after four months of training on their own. Dave Bowman: You're working up your crew psychology report? HAL: [pausing for a few seconds] Of course I am. Sorry about this. I know it's a bit silly. Just a moment... Just a moment... I've just picked up a fault in the AE-35 unit. It's going to go 100% failure within 72 hours.
