Is there a difference in tone between sending a message to a man and not returning it?

There is no difference between these two sounds, because they are no longer pronounced, and the meaning of not pronouncing them is the same, and there is no difference in tone.

It's just that these two ways of speaking have different feelings. In fact, the effect is the same They are all rejecting each other's meaning and not letting them send messages to themselves.

So for some words, sometimes we don't need to care too much about all this. No matter what kind of words we use, as long as we express this meaning, then for us, we just need to respect this meaning and there is no need to think too much.
