Really the world is divided in two: potatoes and grapes.
I am a grape. Sydney is a grape. Husband and Jackson are potatoes. In fact, I am told, most males are potatoes and most females are grapes, though there are exceptions.
Normally you can't be both, though Jackson advises that his Auntie R. is a rare breed and is what can only be described as a grapish potato. (For the record, I think she is clearly a potato.)
