Every cloud has a silver lining

One day the teacher of Maths have marked a test from monday,so everybody hav studied except my friend ,his name is Ricardo this story hapenned last year.
I cleary remember on Saturday two days before the test have ha a big party in the Ricardo's sisters house ,so he haven't studied,everybody have gone to the party but everybody have studied.
Believe it or not on Sunday he didn't study so because he went to the shopping with his girlfriend.
Eventually the day of the test arrived and him haven't studied .To make matter's worse the test was very difficult so he failed in the test.
In the end he learn about this sittuation first the commitments after the entertainments,so for the others test he have studied a lot and pass in every test and pass in the recuperation test of Maths so he up grade the school nivel.
Conclusion Every cloud has a silver lining.
