I'm sorry that you failed your exams, but it isn't a tragedy. You might go to school and talk to your teacher. Maybe he allow you to pass that exams again. Don't worry.
On Saturday I went for shopping in the centre of Warsaw with my best friend Lisa. We bought a lot of clothes and shoes. I had a great time here.
On Sunday I went to the swimming pool. This swimming pool was near the police in Warsaw. I swam with my sister. We were there two hours and I learnt how to swim. On Sunday I had a good time too.
