One day the teachers came to tell us about some things happening in the Sahara, the teachers told us that the people there had to walk several kilometers to obtain water, that their houses practically were of cardboard (some of mud). that's why the teachers proposed us to do a thing: to help them, how to do it? by giving them an oil kilo, a rice kilo and also a sugar kilo.
Only this little contribution, simply that, already is an aid.
