I do; however, that achieves nothing in terms of understanding why it may have been marked as wrong. If I knew the answers to the questions that I ask, I wouldn't be bothering to use Duolingo at all.
The point is that I am learning and do not know if the things I report in fact should be accepted. I greatly appreciate it when you take the time to provide an answer that teaches me something. I think that you are an amazingly generous person for choosing to do so as often as you do, but please don't assume that I ask just to see my words in print.
It would be better if Duolingo provided a response to reports, but they don't, so we must rely on the generosity of spirit and the knowledge of yourself and a handful of others.
