In Britain, birthday celebrations involve a party where everyone brings a small gift. A birthday cake is always made, and there is a table full of food including crisps, sandwiches, small cakes, chocolate biscuits, ice cream, and small sausages served on a stick. The house is decorated with balloons, and party games are played with friends. The author describes this as 'fantastic'.
The text mentions that the celebration is hosted by 'John (12)'.
