Sam"s big brother Ben is going away on a school trip for one whole week - and Sam is glad. Because for one whole week he can play with all the toys, have the whole bedroom to himself and he won"t get squirted by Ben"s water pistol. But it is too quiet without Ben and Sam starts to miss his big brother. So Sam writes Ben a postcard to say he very really misses him and he is surprised to learn that Ben very really missed him too.
