"You are telling me about a new broadcast."

Translation: Ты рассказываешь мне про новую передачу.

[flootzavut]

про my old friend, I have missed you!

[xandnax]

Why is there a need to use про instead of о?

[Jar-JarJac]

There isn't, о передаче = про передачу.

[Oemerich]

"Ты рассказываешь мне о новой передаче" is also accepted ;)

[JeffCat6]

Вы рассказываете мне о новой передаче. Also. Can a native speaker describe the subtle differences? Also good practice for о + prep and про + acc cases.

[PiterPiola]

Does про require acc. Case, or it is the sentence itself?

[keinemeinung]

Correct, про uses accusative.

Why not скажите? And why is вы говорите one possible answer? "You are telling me" sounds like it should be perfective. I think вы говорите would be better if the sentence was "you are talking to me about...".

[Berniebud]

"Вы скажите" is future tense.

The sentence is present tense. Perfective verbs can never be used as a present tense.

Perfective verbs and imperfective verbs are different in how they form future tenses.

While the imperfective uses "Буду/будет/будешь/etc" plus the infinitive to form the imperfect future tense,

the perfective conjugates, in a way identical to the present tense, to form the future tense.

[ElizavetaP19]

Future tense is вы скажЕте. Вы скажИте is a request.
Вы скажЕте правду - you'll tell the truth. СкажИте мне, который час? - tell me, what time is it?

[kpagcha]

Right... stupid mistake. Then what's the difference between говорить and рассказывать?
