Answer:
Remove not, and change never into ever and nothing into everything.
David isn't not isn't grammatically correct. Nobody never doesn't make sense, either, so changing it to ever, a positive word, makes it more grammatically correct. Miss nothing is also a bit strange, so change it to everything.
Hope I explained it to you. :)
Answer:
your answers are not and never
Explanation:
isn't and not are both negatives and this is called a double negative so not does not have to be there and never should be ever because it makes more sense than saying nobody never that is also a double negative so it should instead be ever.
