Gowanheart: If you use the word "lay" in the present tense, you must have an object following, as in "lay a rug." One "lies" on a bed, or "lies" by not telling the truth. One "lies" in the sun. You can lay an egg or lay a pencil on the table; you lie down. If the lying down was yesterday, you can say, "I lay on my bed yesterday." And, I have lain on my bed for months.
Lie, lay, lain
Lay, laid, laid.
My apologies to those who find this unimportant!

Touche'
How about.. I always have the intention of laying on my bed?
Because I am a chicken and it's what we chickens do.
