Grammar review: Me neither./Neither do I./I don't either.

When we have something in common and it's a  negative statement, you can agree by saying,  

"Me neither." This is very conversational.  You can also use "I'm not either"..."Neither  

am I." A more formal way is, "Nor am I."  Remember to use the correct helping verb,  

and you need to invert the subject and verb  when you start with "neither" or "nor." And  

remember you can say /ˈniðɚ, ˈnaɪðɚ, ˈiðɚ,  ˈaɪðɚ/. Let's practice. Agree with me.

I'm not ready.

I'd never do that.

I don't know ancient Greek.

I can't run a marathon.

I won't tell anyone.
