Entre nous

Every invisible line in the mind
Forms its own arbitrary DMZ,
Its own miniaturized shadowland
Where some creatures unknown to either side
Manage to survive. Some beasts tried to cross
But got stuck. They’ve found ways to stay alive,
But they never will get out. Other things
Are born natives of the dividing line.
If the line lasts, some will have evolved there.
Overhead, crossers and transgressors fly.
On either side, the world is on that side,
But don’t you find it more fascinating
Than crossing or maintaining boundaries,
To scrutinize inhabitants inside?
