I worked with a guy once, kinda withdrawn, a little standoffish(is that a word?). I kept trying different approaches to make a connection with him, but he seemed to have no interests at all.
Fianally, after several days, I mentioned something about cars. His head popped up, his eyes opened wide, and he started talking about his car, his friend's car.
For several minutes things were looking good
Then I mentioned the 396ci/425hp '67 Corvette.
He said it must have been the 350hp, because the 396ci was 350hhp.
I said no, the 396ci was made in versions from 250hp all the way to the 425hp.
He said NO, ALL 396's were 350hp!
I said okay.
End of conversation. No intelligent life on that planet.
