Reciprocal Insistence

What does the word contrapositive mean?
It's been a long time since the seventh grade
When geometry was a glimmer in the light bulb
And feelings only knew where to go
As they overflowed onto the floor
Could there be a time ahead or behind
When the spaces between the floorboards

Hold the tears

Cracked open, will we find them if we look?

Is it presumptuous to include you in the search?

Look inside, I will too

What we see, is that all there is?

All I see is a blank

But it depends how I turn the page

And if you're looking too.
