>teeth on edge over the use of the word "lay" for "lie down"

That's just USn linguistic hegemony rearing its ugly head again, Mrs F. The usage which troubles you so is completely standard on the civilised side of the Atlantic. To quote from the late and much lamented Arsenal fan, Douglas Adams:
In reply to:


"Now the world has gone to bed," Marvin droned,
"Darkness won't engulf my head,
"I can see by infra-red,
"How I hate the night."

He paused to gather the artistic and emotional strength to tackle the next verse.

"Now I lay me down to sleep,
"Try to count electric sheep,
"Sweet dream wishes you can keep,
"How I hate the night."
"Marvin!" hissed a voice.
