They're relying on you, not you on them.

Is their reliance founded upon reasonable logic, or are they unreasonably
putting the fault in your court? Depends on the issue...

Many people would not like to need to know these 'under the hood' type

corrupted to teach them the hard way why these 'under the hood' type
details are useful to know... :-)
