Saying things the right way in dealing with people is an art. I'm mostly around computers... kind of like a lawyer who comes home and then deals with his family by continuing the cross-examinations! Thanks for pointing it out; I was thinking about it the other day -- multiple ways to phrase the same thing -- and it took me several iterations to get from "likely offensive" to "non-offensive and helpful". I don't have enough experience with humans to say things the right way right off the bat, so I may need to essentially run unit tests on everything beforehand until I develop my intuitive sense to a much greater degree.
With computers you tell them "here's exactly what's wrong with you." With humans you can actually rely on them to fill in the gaps and just state things a lot more diplomatically (not to mention, it's not about making people "wrong" anyway!). Something phrased very gently and ambiguously can get results, and is probably the only way to deal with people effectively in most circumstances. I appreciate the reminder!
