Belinda (happily). Have I?

Delia. Yes; it's serious this time. He's not like the other two.

Belinda. However did you know that?

Delia. Oh, I know.

Belinda. Darling, I believe you've grown up. It's quite time I settled down.

Delia. With Mr. Robinson?

(Belinda sits up and looks thoughtfully at Delia for a little time.)

Belinda (mysteriously). Delia, are you prepared for a great secret to be revealed to you?

Delia (childishly and jumping on to the L. arm of the Chesterfield facing Belinda). Oh, I love secrets.

Belinda (reproachfully). Darling, you mustn't take it like that. This is a great, deep, dark secret; you'll probably need your sal volatile.
