SO DO I!

I use 'so do I' to say that a positive sentence is also true for me, and I use 'neither do I' to say that a negative sentence is also true for me: John: I hate mushrooms. Me: So do I (=I also hate mushrooms). Lucy: I don't live in London. Me: Neither do I (=I also don't live in London. For example, maybe Lucy and I both live in Paris).
