Right here, there is a boundary.
It may not at first be so clear,
for the vestibule seems over the horizon to disappear.
When your feet course ‘cross this threshold,
I will bid you a courtesy warning.
To trample over it, carelessly, I will on the next offense bid you adieu.
Flirting repeatedly with this line will bring multiple yellow cards,
Careful there, for yellow cards can turn red quickly & without warning.
I’ve toiled to tear apart many fences & take down walls to know you (me, too).
Respect the thresholds or your knowledge of me will be merely a distant, foregone memory.
