Billing. May I mix a glass for you?

Petra (coming to the table). Thanks, I would rather do it; you
always mix it too strong. But I forgot, father--I have a letter
for you. (Goes to the chair where she has laid her things.)

Dr. Stockmann. A letter? From whom?

Petra (looking in her coat pocket). The postman gave it to me
just as I was going out.

Dr. Stockmann (getting up and going to her). And you only give to
me now!

Petra. I really had not time to run up again. There it is!

Dr. Stockmann (seizing the letter). Let's see, let's see, child!
(Looks at the address.) Yes, that's all right!

Mrs. Stockmann. Is it the one you have been expecting go
anxiously, Thomas?

Dr. Stockmann. Yes, it is. I must go to my room now and-- Where
shall I get a light, Katherine? Is there no lamp in my room
again?

Mrs. Stockmann. Yes, your lamp is already lit on your desk.

Dr. Stockmann. Good, good. Excuse me for a moment--, (Goes into
his study.)
