Blood Points the Way

Blood points the way
Amber says get ready
Green, go
But there is a barrier
A right-angle
A triangle
A holy trinity preventing
The solution
Instead watermelon minds
Meld their answers
Into them and us
They are the ones
Who know best
Keep us apart
By a borderline
A tramline
Parallel lines blurring
Searching for an answer
To a pandemic riddle
Where the only response is
Who knows?
