The sentence: Talk to them, and you should tell them the truth.

In 1-2 sentences, identify the shift in mood and rewrite the sentence correctly.

(Completely original, and like an 8th grader wrote it)

I'm not really sure here, but I think there could be a shift from a demanding to a more friendly tone. So, maybe it could be like "Hey, why don't you talk to them and just be honest."
