I have very little sense of what an actual weasel is. It’s an animal that gets much more play as a metaphor than as an actual animal.
Is it like a ferret a little bit?
Or is ferret another name for a weasel- weasels having developed such a bad name.
How did weasels become weasels? Are weasels particularly weasely? Are they sneaky and duplicitous? What did they do to deserve such an unsavory reputation?
