One hand for the nose

3yo: Mira didn’t want to hold hands anymore today (at the school trip to a Provincial Park).
me: Why didn’t she want to hold hands?
3yo: (looking perplexed) She wants to hold the teacher’s hand.
me: Oh, that’s ok. Did you hold hands with another friend?
3yo: But mommy, one hand is for holding hands, and the other hand is for picking the nose!
