At least, I assume that was the reason, that she doesn't think I have an unnatural interest in sheep per se.
I thought my response to her message was worthy of a top-level post here.
Poetic sheep! the perfect plan:
Since sheep are very dense,
They free me from the need to scan,
To rhyme or to make sense.
And once I've filed the verse away,
Ere I dismiss the sheep,
I'll count them, in the hope that they
Will send me off to sleep.
