UNIT 3. GRAMMAR A
SO/NEITHER/NOR DO I
So + be/modal verb/auxitiary verb + subject mean 'in the same way', 'as well' or 'too'.
Example:
A: My brother is a newsreader.
B: So is my dad. (= my dad is also a newsreader.)
A: My grandparents get some dose of sad news everyday.
B: So do my parents (= my parents also get some dose of sad news everyday.)
A: I must find ways to stop doomscrolling.
B: So must I. (= I also must find ways to stop doomscrolling.)
***
Neither/Nor + be/modat verb/auxitiary verb + subject mean 'also not'.
Example:

B: Neither/Nor is her brother. (= Her brother isn't a good listener.)
A: I can't watch a movie if there is violence in it.
B: Neither/Nor can my sister. (= my sister can't watch a movie if there is violence in it.)
A: I don't like watching sad things.
B: Neither/Nor do I. (= I don't like watching sad things.)
Note: We also use ... not either when we want to give a negative meaning:
Example:
A: She isn't a good listener.
B: Her brother isn't either. (= Neither/Nor is her brother.)
Common mistake: Her brother isn't also.
A: I haven't ever used my phone more than an hour a day.
