Questions about some parts of Brothers Karamazov which I can't understand

[Milan]

I'll post my questions here.

[Milan]

‘Have you heard our news?’
said the mother, pointing
at her daughters. ‘It’s like clouds coming over; the clouds
pass and we have music again. When we were with the
army, we used to have many
such guests. I don’t mean to
make any comparisons; everyone to their taste. The
deacon’s wife used to come then and say, ‘Alexandr
Alexandrovitch is a man of the noblest heart, but Nastasya
Petrovna,’ she would say, ‘is
of the brood of hell.’ ‘Well,’ I
said, ‘that’s a matter of taste; but you are a little spitfire.’
‘And you want keeping in your place;’ says she. ‘You
black sword,’ said I, ‘who as
ked you to teach me?’ ‘But
my breath,’ says she, ‘is clean, and yours is unclean.’ ‘You
ask all the officers whether my breath is unclean.’ And
ever since then I had it in my mind. Not long ago I was
sitting here as I am now, when I saw that very general
come in who came here for Easter, and I asked him: ‘Your
Excellency,’ said I, ‘can a la
dy’s breath be unpleasant?’
‘Yes,’ he answered; ‘you ought
to open a window-pane or
open the door, for the air is not fresh here.’ And they all
go on like that! And what is my
breath to them? The dead
smell worse still!. ‘I won’t spoil the air,’ said I, ‘I’ll order
some slippers and go away.’ My darlings, don’t blame your
own mother! Nikolay Ilyitch, how is it I can’t please you?
There’s only Ilusha who come
s home from school and
loves me. Yesterday he brought
me an apple. Forgive your
own mother — forgive a poor lonely creature! Why has
my breath become unpleasant to you?’
