I'm starting to notice questions of this kind more and more often. It seems to me that what most people want is to ask us to allow them to do whatever they want to do but not exactly answer their questions.
They ask us whether they can do/say/write/speak something instead of asking whether it is correct and appropriate to do/say/write/speak something.
A crude instance:
Can I write this? "My need now blue pen"
The adequate answer should be, "Yes, if you want you can". And this is a proofreading question, which is off-topic.
But in fact the question asks whether it is correct and appropriate to write something like this, whether it obeys grammar rules or is accepted in any way.
So why do users most often ask us for permission rather than explanation?
