K's Point of View: I don't like that song

On the eve of K's birthday, DH was putting her too sleep, singing her a lullaby. I noticed she was tearing up. I asked her why she was tearing up... she was quiet for a few minutes, until I gave her a hug and asked again. DH and I were seriously disturbed.

K: Kasi (because) I don't like that song.
Me: Oh. Why, what song do you like?
K: Happy Birthday.

We love you K. The memories you give us are all priceless.
