How it works
An emergency fund is coins kept for things nobody planned. Nico keeps his in a jar on a back shelf.
A fund is often a few months of costs. Nico's costs are 20 coins a month, so three months is 60 coins.
When a storm cracked the window, the repair cost 15 coins and the storm kept customers at home. The jar covered the gap, and the shop stayed open.
A surprise is still a surprise, but a jar makes it a smaller worry. A grown-up can help decide what counts as an emergency.
