Which one?

Ever since Iki was born, this "which one" question is often raised in our home.
Like last night, when I forgot to prepare Hiro's night wear after he's bathing Iki.

Hiro: It's OK. I know you ONLY love Iki
Me: Soorrryyyy. I love you both. It's just you've finished bathing him when I was about to take your cloth from the closet.
Hiro: Hahaha what an excuse :p. If both Iki and me got drown, which one will you save?
Me: Of course both of you! I can't choose one
Hiro: Really?
Me: YES. Hmm what if Iki and me got drown? which one will you save?
Hiro: Of course Iki hahahahaha

[My mind was: WHAT?!?!]

What a blunt answer! (_ _o)
But eventhough he saved me, I'll definitely ask him to save Iki instead

I will give my life for him, if needed.
