Why do you seem frightened, Stepan Trofimovitch?
I only tell this from his drunken chatter though, he doesn't speak of it himself when he's sober.

He's an irritable man, and, so to speak, aesthetic in a military style; only he has bad taste.

And this sister is lame as well as mad.

She seems to have been seduced by some one, and Mr.Lebyadkin has, it seems, for many years received a yearly grant from the seducer by way of compensation for the wound to his honour, so it would seem at least from his chatter, though I believe it's only drunken talk.

It's simply his brag.
