A year or so ago, one of the guys in our IT (I.S.) department, a young fellow of 25 or so, asked another IT guy how to spell (phonetically) "post". "Post?" "Yeah, you know: I'm post to stop at the store for milk on my way home."
Gaaah!
Another time, I encountered the whole group of them - ranging fomr 25 to 50 years of age - standing around. When I walked in, someone said "Ask JonnyB; he'll know". "Know what?" "What does BTU stand for?" Y'all are shittin' me, right? In a group of 6-7 adults, none knew it. One had the gall to tell me "I'd never have guessed that." I responded that I didn't guess; I knew.
