In this email I would like to tell you what occured to me in Italy during the summer vacation last year. So, I went to Italy for four days. First I stayed in Firenze, than I decided to go to Rome.
I slept in the jungle lodge. Dinner was really nice as there was only one restaurant were everybody gathered. My newly acquired friends invited me to join them for dinner and we had a great time.
One could see the animals from a distance. There were sea lions, whales and penguins, all very far away. In the evening we went on a boat for whale watching which was a really great experience.
