Please take a look at this question (10k+ only - OP finally deleted it), and read some of the comments (just read a few - you don't need to read them all, we've literally gone around in circles). Essentially the question was a homework assignment with the whole question consisting of a copy & paste from his teacher.
I wrote a fairly concise comment asking the OP to try something, come back when he was stuck, and post up a specific question.
The OP decides to berate me, telling me I'm wasting his time, and that the reason for all of the downvotes is because of all of our back-and-forth in the comments.
There were about 15 messages or so exchanged, and I kept on-point and matter-of-fact, even after he insults my intelligence and development skills.
I'm 99% sure I'm in the right here, and 5 other downvoters seem to agree.
I already flagged the question before I made my first comment.
I know I'm not perfect, so that's why I'm asking this question: How would you have handled this particular situation?
