Rings

The other day for story telling, "Presents for Mum", the story was about Dad getting Mum a wedding anniversary party and the present was a ring.
Teacher: Look, what's inside the box?
Shyira: A ring!
Teacher: Yeah, looks like Dad got Mum a ring, and Mum got Dad a ring too. So for their wedding anniversary they exchanged rings.
Shyira: And they will get married!
Teacher: No they won't get married because they are already married.
Shyira: Then they will have children!
