frumiousb kindly sent us some Dutch knick-knacks including a small yellow clog with wooden tulips. Now this clog is bright yellow and has a sort of tip at the end that does look like a kind of duck's beak. This prompted the following conversation between me and Special K
Special K: Why does that duck have tulips in it?
Me: It's not a duck. It's a shoe
SK: It's a duck. It's yellow.
Me: It's a special shoe from Holland.
SK: No, it's a duck. This is a shoe. (She brings me one of my shoes. A large brown Mary Jane shoe.) This is a shoe.
(She points to the clog.) This is a duck.
Me: (bursting into laughter) It's a yellow clog.
SK: (laughs too) No, it's a duck!
