why do they use subjunctive in this sentence?
hey i was watching arnold schwarzennegers movie "colateral damage" and i was watching it with subtitles, and one time the guy said "NO ME DIGAS QUE HACER"
the subtitle said "dont tell me what to do" but i dont understand why he used subjunctive DIGAS, instead of DICE. i know what subjuntive is and i know how to use it, but to me it just seems like they use it TOO much. why do they say "NO HAGAS ESO"?? insted of no hace eso?
also, why do they use "Usted" so much when they're only talking to someone that should NOT be formal, tu (with an accent mark about the u)? like a husband to a wife, or vise versa?
"NO ME DIGAS QUE HACER"
the subtitle said "dont tell me what to do" but i dont understand why he used subjunctive DIGAS, instead of DICE
The subjunctive is used with negative commands
• Don't tell me - no me digas (negative command)
• Tell me - Dime (positive command)
Trust the other answers in regards to the commands.
To answer your second question, it depends on the culture. For example, there are some places where children will use "tú" with their parents. People in other cultures may address all adults with "Ud."
Hope this helps.
In this case hagas is not subjunctive; it's the negative command form. "Haz"--do it; "no hagas"--don't do it. Hagas and digas are also the present subjunctive tú forms.
