Boy or girl?

Gender is a social construct.  When boys and girls act like their stereotyped roles it's because society has conditioned them to act one way or the other based on their gender.  But ultimately a kid is a kid, and it's hard to tell if one's a boy or girl if you have them dressed and coiffed the same way.  Why must girls be treated as delicate beings while boys are often encouraged to be more physical and strong? Like I said, a kid is a kid.

Try to guess the gender of this real child based on these facts:
- favorite color is pink
- favorite book is written by Stephen Hawking
- dressed up as Darth Vader once for Halloween
- concerned about getting fat/eats healthy
- enjoys playing soccer
- small for age
- likes to sing (likes to show off in general)
- a self-proclaimed artist
- likes gardening
- has scraped knee several times
- aspires to grow up to be some kind of scientist

Have I made it ambiguous enough, or is it too easy?
