Which Begs the Question...

[Kitsa]

Completely valid woes, but you'll have to be careful lest you turn into Seth.

Where I used to work, there was a physician who constantly used "in lieu of" to mean "in light of". In terms of temper, she wasn't one to be messed with, and everyone was afraid to say anything about it. I thought the same as you did..."this person who can apparently grasp sophisticated scientific concepts cannot differentiate?" I would look at my supervisor every time she said it. He would give me a warning look, and she went on to use "in lieu of" instead of "in light of" in speeches and Grand Rounds.
