What do you want?

Sofia always asks me this, though she is actually telling me to ask her just that, but whenever I answer with my choice, she would 100% choose something else - and insist on it. She has become an individual now, making a lot of the basic decisions in her simple life - what to wear, what slippers to use, what color of M&M to eat, what game to play, what book to read and the list goes on. I still win over when its time to go to bed, though not without much resistance and No's from this little girl. 

Seating here, looking at her - my 2-year-old baby - made me think of this question, "What do you want?" and I'm still struggling for an answer.
