But nature doesn’t always respect those boundaries.
Small creatures can enter through tiny openings, arrive accidentally on clothing or objects, or simply find their way into places where we never expect to see them.
And sometimes, all it takes is one strange discovery to make us realize just how much we normally take for granted.
Looking back, I still remember the moment I first saw that dark shape on the floor.
At first, it was nothing.
Just a piece of trash.
Then it became a strange object.
Then something that might be alive.
And finally, I discovered what it really was.
A leech.
The discovery itself lasted only a few minutes, but the feeling stayed with me much longer.
