Dear Diana,
My family and I are having a rest in Italy now. The weather is sunny, the sky is blue and no wind. My brother and Dad are playing chess on the beach, Mum is reading a magazine in the shade. We have already swum in the sea and now we are having a rest on the seaside. I'm watching seagulls flying over the sea and writing this postcard to you. Yesterday we went on an excursion and saw some interesting sights here. We like Italian people and Italian food. I've took a lot of pics. How are you getting on? Write back soon!
Best wishes,
Alex
