Actual conversation had a few weeks ago....

[conuly]

Ana: Connie?
Me (reading a book): Yeah?
Ana: (I have no idea what she said)
Me: Mmm-hmmm....
Ana: Connie! I don't like it when you say "mm-hm" because I think you're not listening to me!
Me (closing and putting down book): You're right. I wasn't listening to you. Now. What did you say?
Ana: I said, I don't like it when you say mm-hm, because it's like you're not listening.
Me: Yes, I got that. But what did you say?
Ana: *sigh* I said that I don't like it-
Me: Ana! I know, I heard you! But what did you say before that?
Ana: I didn't say anything before that.
Me: Yes, you did.
Ana: No, I didn't. I'm serious.
Me: But... but... but... *sighs* Fine. I'm going back to my book now.
