but you cant be completely ok, something will always be wrong.
if you say i don't care, you responded or at least acknowledged it, so u do.
you don't know, but you have to have some thought on it.
okay what if someone asks you what restaurant you want to go to, x or y. X and Y are your two favorite restaurants and you have no preference. You say, "I don't care." Wouldn't that be an example of a situation where you actually didn't care?
another example: your mother asks where your sibling is. you haven't seen them all day, and they never said anything. you woke up and they were gone. Isn't, "I don't know," completely true in this situation?
