Gert. A certificate of health. You see, it is necessary to be a

Olof. How did you get it?

Gert. Don't you think I deserve it?

Servant. Will you please go your way. They 're about to sweep.

Gert. Perhaps the place has to be aired, too?

Servant. Yes, indeed!

Gert. Don't forget to open the windows.

Servant. No, you may be sure, and it's needed, too, for we are
not accustomed to this kind of company.

Gert. Look here, old man--I carry a greeting from your father.

Servant. Oh, you do?

Gert. Perhaps you never knew him?
