My wife teaches eighth grade. Her feeling about “there are no dumb questions” attitude is, yes, sometimes there are dumb questions (especially from jr. highers). When it happens, she jokes with the student in a “we’ve laughing with you, not at you” sort of way. And knowing her, the situation for the student and the classmates becomes a positive bonding experience.
So, @Truckman, although I had a good laugh, it’s with you, not at you! I’m plenty guilty of equally or worse “dumb” observations. What I really enjoyed is your “they are way too cool” comment. I totally agree. If only there were more innovative companies like WYZE out there.
