Will You Ask Questions When You Really Want to Know the Answer?

We were going to a public program about our interest (but we don't).
We discussed online as we don't meet.
But then there was a time to meet,
so we continued our discussion on whether to go or not.
So, like, any person nearby will caught up what we were talking about.
And asked,
"What're you talking about?"
"Where're you going?"

So, what would you expect us to answer?
Of course, we'll say
"To a program which teach us of (our interest)"

Well, some of them, I know, would reply on our answer,
"I see"
or something.

But, I know, some of them would
"Well, like I care"
"Doesn't matter to me"
"Oh. Whatever"

Like,
what the hell?
You were asking,
we answered,
and you replied like we were DESPERATELY WANNA TELL YOU?!

So then, I took a decision to
- answer a friend with
"Well, I know you wouldn't care but I'll eventually tell you,........."

- ignore

- half-answer

- answer then ignore

Done.
Farewell.
