>>I already did. Also, no. Just because you know something is bad, doesn’t mean you know a better solution, so it doesn’t automatically follow that a better solution should be given.

>You can just say you've no idea about it,

That’s true (i.e., I can say I have no idea about it), but I have no reason to lie about it, so I won’t. I did have an idea, and I gave the idea to you, as I mentioned in my two previous replies.

> such situation doesn't need to write so many words to explain it to me.

Paraphrasing you: “I don’t really care about whether you are better at efficient writing than me, I just need to get my message across (without information loss)”.

> I don't really care about if you know better than me, I need to know how to solve the problem. 

And I told you how to do so. Also, well, you are the one that (multiple times, IIRC) brought up “who knows better than who”, not me.

>If you can briefly reply just like what I quoted, without writing so many words that I never take a look as you may realized it already. That is the meaning of "save my time", and of course saving yours.

No. Misreading another persons words is not the meaning of “save my(/your) time”. (_Not_ reading another’s words can have the same kind of effects as misreading, so I’m including it in “misreading” for purposes of the previous sentence.)

Not reading before answering wastes _everyone_ time. Reading is much faster than writing (almost instantaneous compared to the other activities), so in case of a limited audience(*), clarity of writing and speed of writing becomes a bit more important than how fast it is to read. All those words I write, are there for a reason: to answer the questions, to respond to other remark, and to be precise about it. Also, this writing style is natural to me, so doing it different would cost me time. Compactening those words into less words might be possible, but takes a lot of time(**) and can easily lose relevant information, so unless it’s for a wide audience(*), I don’t, which saves time.

(*) various exceptions apply

(**) like, writing this mail took my about 45 minutes, and that’s without any compactening. Yet, it can be fully read in less than a minute. And even if I were to beforehand select parts to only those part, this selection process still needs time, and those other parts would remain unanswered.

Also, when I (of my own volition, and in absence of external obligations competing for time) _choose_ to spend some extra time on writing beyond necessity, then it’s up to myself whether to consider this extra effort ‘waste’ or not, or perhaps even ‘valuable for its own sake’.
