The nature of answers:
I don't know is an answer, and so is I DON'T CARE.
Sometimes I have said I don't care as "it doesn't matter" which I suppose is more advanced statement, but could also sound like oh shut up it doesn't matter so instead of saying that I just probably might say nothing because I don't really mean shut up, I just mean, do you think this matters, because so far my sense of the thing is that it might be of little consequence but what do you think.
I don't know is a good answer. It can be qualified, analyzed too, and thus yield a lot of information.
We don't care, I don't care, it doesn't matter, is often a good answer too, and I'm thinking now of Dr. Kim teaching us "don't care variables" in Digital Systems (Electrical Engineering) at Howard University. But how do you say that to a person who doesn't interpret it that way, who doesn't translate technical language? If they're, like, artistic, you might go with, oooh yeah, there are lotsa options! That would probably be right. Say, I agree. Then go into more possibilities. By the way, many artists develop the same sort of compact language as they get more technical or more advanced, so it all depends on how "old" they are, in this learning direction?
Now if they're also not artistic, do you say something like "fantastic!" and run away? Yes? No? Sometimes? I mean, that does lead to problems lol. If it's not fantastic, you say fantastic. If it is fantastic and you therefore want to look closer you don't say fantastic you ask more questions. If you record the tally then the least fantastic get the highest fantastic rating and the most promising are dead.
