[link|http://z.iwethey.org/forums/render/content/show?contentid=11576|...when Jo comes in, finds the PC booted into Linux, decides she wants to read her email (she has it all set up on the Windows side of things) and hits "reset".]-- How the fuck can you tolerate that?!? (From a putatively adult and reasonably intelligent person, I take it -- or are you dating a retard?) That's just no way to behave with a computer!
What should also have been fuckin' obvious is that I meant, not necessarily *literally* slapping her around, but give her a fucking strong talking-to: "That's just no way to behave with a computer!"
Just show her how to shut it down -- you usually run Linux with a GUI on, don't you? So it isn't even all that different from how you do it in Windows -- in an orderly fashion. And then you can tell her, "*This* is how to behave with a computer!"
