Clo. Where you shall be the quicker if while here
You can keep silence.
Fife. I may whistle, then?
Which by the virtue of my name I do,
And also as a reasonable test
Of waking sanity—
Clo. Well, whistle then;
And for another reason you forgot,
That while you whistle, you can chatter not.
Only remember—if you quit this pass—
