Imagine that you live on an island, where you have to walk through a forest to go to school. You carry a big container of water day because water is scarce at school. Your afternoon snacks are boiled cassava and titi corn, instead of biscuits and apples. After the lessons are finished, you have to clean the classroom because there are no cleaners in the school. But if you can finish the cleaning early, you get to play with friends on the beach.
