I've just learned a very basic way of shortening sentences:
He likes tea (positive), but she doesn't (short negative).
I haven't got a car (negative), but my sister has (short positive).
But, what about:
She doesn't like coffee (negative), but I do (short positive).
According to google results this seems not very usual. Only got 6 results for the search phrase "doesn't like coffee, but I do".
I am wondering, is the sentence above correct? or shall I have to say:
She doesn't like coffee, but I like. (?)
