And so we leave on our deadly journey. While waiting for a ship in Copenhagen, uncle thinks I should practice climbing church steeples.

I don't mind the idea of climbing in a narrow cave, but I'm terrified of heights: I get dizzy and could fall off! But uncle says I need to build up confidence and strength.

Should I climb the steeple and risk falling off? Or refuse to climb and risk being unfit? Or do something else?
