I am still cracking up about this...
A lady at the seminar, very new to herding, told me her thoughts on "heavy vs. light" sheep:
She said "I don't see the difference. They all look about the same size to me."
Of course, she had figured out the difference, but when she told me her initial thoughts, I about died! She was a riot! We've actually shared lessons with her the past 2 weeks.
