The Fruit

There was a guy that dont like anything & blame god on everything ... while walking in the forest he saw a big pin tree , that have small fruits , so he said , god didnt make it well , there is an error in it , how can a such big tree give such a small fruit ?!...
Then , he saw a small vegetable , that is giving rise to a big fruit & he repeted the same words , god commit an error in making it ...
When he returned , he slept on the base of the big tree ... while sleeping , a small fruit fall down from the tree on his head ... he woke up saying , thanks god that this big tree has small sized fruits ...
