– Sh! There’s a burglar behind the curtain!
– Are you certain, Bertha?
– Don’t disturb him! He might hurt us – or worse, he might even murder us!
– But are you perfectly certain it’s a burglar?
– Perfectly. Only a burglar would hide behind a curtain in that way.
– Oh, Bertha – do you remember Percy Turner?
– Sh! Gertrude! We’re not the girls we were thirty years ago, you know.
