There is a first grade class in Budapest in a wealthy area where the kids support the kids of another first grade class from Biharkeresztes which is located in one of the poorest regions of Hungary.
At christmas everyone from Budapest packed a shoebox full with their toys.
This time at the end of the school year they chose their favouite book and sent them to their pairs.
Because each kid has a pair. They did not meet yet but the teachers are in contact and arranged pairs upon the individual kids characters.
