By popular demand, here is another grammar refresh.
“Lay” means to place something, whereas “lie” means that the object of the sentence can lie on its own.
I will lay my blanket on the bed before I lie down.
A trick I use to distinguish between these quickly is to use the word “place” as a substitute. If you can say “place” then you can say lay. If not, then it’s lie.
I will place my blanket on the bed before I place down. See how this works?

We need to look further into this topic before we write the paper.
We walked a mile farther today than we did yesterday.

I set the vase of flowers on the table.
I sit in the chair.
Trying the “placed” trick can work here too.
I placed the vase of flowers on the table.
I placed in the chair.
Again, since “placed” doesn’t work in the second example, you would use “sit” as the verb.
I hope I helped with a few bugaboos! Happy writing!
