I understand a gaggle of geesebut a conclave of cardinals?
Well, you're ahead of me. I don't even understand a gaggle of geese! It sounds like the geese all have little gags over the beaks. As far as a conclave of cardinals, is that like the Bat Cave? Lol!
I also wonder who makes up these phrases, most make no sense. Just like a group of crows is called a murder of crows, what????
