As if I didn't know!

KATERINA.
Ah, Varia, there is sin in my heart! Alas, how often I have wept, I have
done everything I can think of! I can't get free from this sin. I can't
escape. Varia, it is wicked, it is a fearful sin--I love someone else!

VARVARA.
I'm not likely to be hard upon you! I've sins enough of my own.

KATERINA.
What am I to do? I'm at the end of my strength, where can I find help. I'm
so wretched, I shall do something dreadful.

VARVARA.
Mercy on us! what is coming to you! Come, wait a bit, brother's going away
to-morrow, we'll think of something; maybe, you'll be able to see each
other.

KATERINA.
No, no, that must not be! What are you saying! God forbid!

VARVARA.
Why are you frightened?

KATERINA.
If I were once to see and speak with him, I should run away from home, I
would not go back home for anything in the world.

VARVARA.
