Is "Big Mo" a good egg ?
At the moment, she is. Until she says or does something stupid.
Big Mo's advice about unwashed eggs is one of those things I've heard all my life.
I'm sure I've also been told the "why" of it, but as my "hearing" tapers off after the first half-sentence or so, I never grasped it; only that unwashed eggs are better than washed ones.
