We are having a wonderful holiday. This really is a great place. I have never been
anywhere like it before. People are friendly, the food is great, and the weather’s a lot better then at home. We have been here for ten days now, and we have sun every day. Can you believe it? I swim two or three times a day, but Bill just spends all his time lying on the beach with his eyes closed. Sometimes he writes a postcard, but then he forgets to post it.
Last Saturday I got on a bus and went to the north end of the island. It is very beautiful. Tomorrow we are going to the east coast to see some of old villages, if Bill wakes up in time. And next week, if the weather is still nice, I think I will do some walking in the mountains.
