I have many native English friends I talk with and I have noticed one thing among them: they use question tags (not quite question tag but more of a rhetorical question) in a different way. For example, they will use "she does?" instead of does she? when you tell them something like "she likes apples". So the conversation can be illustrated as:
You: She likes apples
Addressee (native English): she does?
Another example:
A: she has told me the truth.
B: she has?
Surprisingly, I recently watched "Sherlock Holmes" and came across such kind of questions a lot, particularly in "A scandal in Belgravia".
My question is: is this common among native English speakers to use questions like that? How often do you use them in real life? Is it considered a rhetorical question?
