Thank you Tdol. May I ask if you are an English-speaker? I'm asking this, because my mother tongue is Spanish, but I've been studying English all my life, and they taught me that in order to ask a question you need the
inversion verb-subject. However a lot of people to whom I asked if both questions are correct, they said both are correct. This does not convince me because why was I taught (and in fact, it is still being taught in this way) thay way of asking a question and not told that we can ask a question in the Spanish way >> "you are sure?". Even in German you need the inversion.
This is very strange for me.
