Once a month, kids in FatLand host their classmates for a meal at their houses. Parent(s)/Guardian(s) puts out a spread, with the help of people who do exactly this for a living - they plan events and social occasions and meals. They even do the invitations. The only thing the parents and kids have to do is decide what they wish to serve. They take into account food preferences and allergies, but most hosts take pleasure in providing a wonderful and multifarious spread. This way FatLand kids get to experience a variety of foods and tastes and cultures.
The wonderful thing is that it is all paid for by the Education Fund.
