You must not eat the last pawn!

Dominic and Pia enjoy playing chess.  They seem to have received the belief that capturing an opponent's last pawn is very bad form.

Daddy's opinion is that the children will learn best if he does not play easy with them (he's not really very good in chess anyway), so gives no notice to this strange belief.

Daddy and Pia playing chess.  Daddy capture's Pia's last pawn:

Pia: (indignant) Daddy! You must not capture my last pawn!

Daddy: Why?

Dominic: (near sobbing) You must not capture the last pawn.

Daddy: But why?

Pia: (now crying) You must promise not to eat my last pawn. I don't want to play anymore!

Daddy: (still confused) Why?
