Could you explain what "No, not Anna" means? If I am right, "No" means that Anna can't go to the party but what about "not Anna"?
- Did you invite guests to our party on Saturday? ... Anna?
- No, not Anna. She said she didn’t like parties and couldn’t dance.
PS. Before Anna there was some phrases about another man. There is only "No".
- What about Stephen?
- No. He said he had a few days’ holiday and (he) was going to Italy.
I don't understand the difference.
TIA
