Has the guy already brought the boots in???
This is what someone standing in the kitchen (Mother?) might say to a person
who is entering the kitchen from outside the house wearing muddy boots.

This usage of the word "you" is not technically correct,
but it is a dialectally accurate representation
of the way people speak in some areas.

It is a regional or a cultural colloquialism, and somewhat obsolete.

The word "you" may be seen used in this way in literature or movies
to give the speaker's dialogue a regional tone or style.

This usage of the word "you" should not be imitated by English language students.

The YOU in this sentence adds emphasis to the command, Mother's pointing finger.

Don't you bring the muddy boots into the kitchen!!

Hello Affix,

I decided that I had to say more to you about this question,
so I just spent quite a while editing my original, hasty reply.

Now I really understand. Many more thanks. [Y]
