Ez guys, it's ez

You lie down in bed, always, not lay down in it.

no one said lay in it. The post says lay on it which means not under the covers.

If you exclude the meaning "to tell an untruth" and just focus on the setting/reclining meaning of "lay" and "lie," then the important distinction is that "lay" requires a direct object and "lie" does not. So you lie down on the sofa (no direct object), but you lay the book down on the table (the book is the direct object).

Thank you.

What about if I eat some Lay's chips? Did I get Laid?

Then you have a crunchy mess that's impossible to sleep on
