Don't worry, I was in no way offended.

Alerting the user the Facetime was turned off when a Facetime call to them was attempted would be a very bad idea. You'd then need a setting to tell the phone not to alert you for people who really wanted Facetime turned off...

I guess if it only notified you the first time it wouldn't be so bad.

I think they should definitely do what I suggested and add a Facetime button to contacts even when you had Facetime turned off that prompted you to turn it on when you tapped it. Otherwise Facetime is completely invisible in the UI unless you notice the single option in Phone settings. Facetime is very much 1.0 at the moment, I expect these bits will improve with time.
