> Nobody ever says anything bad about laying down Really? Then let me be the first: IT'S "LYING DOWN", FFS! You can be laying down the law, but on a bed you are usually "lying down". This has been a public service announcement, et cetera, et cetera.
The past tense of "lie" is "lay", which is where the confusion comes from, whereas the past tense of "lay" is "laid". Handy chart[1].
After I laid bricks this morning, I was tired and lay down.
Not: *After I layed bricks this morning, I was tired and lied down.
