You've never seen "simple" used as a noun? Is English your first language?

It's not a matter of me "lightening up," it's more of a matter of usage. I'll sit here all day and teach.

You've never seen "simple" used as a noun? Is English your first language?

Yes, and I managed to do very well in the subject.

I guess Merriam and Webster don't know the meaning, either.

Please enlighten me. Other than the out of using it as a proper name, please enlighten me as to how "simple" is a noun. Even in the poem "Simple Simon" simple was used to describe Simon, in other words, an adjective.
