You're the hidden princess, people know that you exist, but they have never seen you before, you're 16 years old.

Sometimes you sneak out of the castle and go into town, dressed like a peasant.

You were walking down the road dressed like a peasant and this shopkeeper walked up to you and said "Get out of here you poor little peasant!". The things that you normally wore outside the castle normally made you look poor. This boy who looked around your age yelled "Dad! Stop it!" to the shopkeeper.
