Love/Hate interchange

In the playroom, while I’m folding laundry in the living room a few feet away…

K: Braska, are you silly?

B: No, I’m happy.

K: Braska, do you love me?

B: No.

K: Why do you not love me?

B: (Almost sweetly) Because I will hate you… (See here for more on this odd response…)

K: You hate me???  (Pause) Braska, we don’t say hate. We don’t say that word.

Then the play continues.

No hard feelings.

(Any input on the strange “why” response always being the “hate you” thing?  Feel free to share.)
