This Far & No Further

There is a symbolic line in the sand
That I have drawn to mark the limit
Of my tolerance and patience.
The infrequent times that I, or others,
Have over-stepped that line
Are occasions of regret.
They signify a loss of control by me
Or a misunderstanding by others
Of what that line signifies.
“Good fences make good neighbours”
Is wisdom beyond mere words.
I am who I am.
If you cannot recognize this truth,
Then approach no further.
I’ve been known to bite.
