pink vs. blue

Long ago when E was 3-ish, she and I were playing "Rock, Paper, Scissors."

Instead of putting out her index and middle fingers to give the international symbol for "scissors" she only used her index finger.
I stared at the didget and asked, "What's that?"
She contemplated the finger for a beat, and then replied, "A tulip stem!"

J had the same misfire the other day, and I asked what his lone finger represented.

He quickly replied, "A knife!"

We never established what beat what in terms of either gesture, but I thought it was quite telling from a nature vs. nurture standpoint.
