But siriusly Mike, it's like dating, not like marriage. You WANT to go out with her again, but for whatever reason you can't. So you make it sound maybe more "inescapable" than it really is so that you convey your interest in definitely having a next date.
I mean, you call somebody up for a date, wouldn't you rather hear "I've got something I can't get out of this Saturday, but I'd really love to see you again soon." or "Not this Saturday, there's something I want to watch on TV..."?
We're all human, alive to subtext and nuance, even if we invent stuff that's not there...
