We can say:
I didn't do it
Some other guy can say:
Neither did I
And we get such a scheme of such negation:
"Neither" + "auxiliary verb" + noun
But what if to complex it a little:
We talked with neither her nor him
How to say that they (she and him) didn't talk with us, either?
Is my variant correct?:
"Neither" + did(auxiliary verb) + "neither she nor he"(noun)
Or it would be so:
"Neither" + did(auxiliary verb) + "either she or he"(noun)
