III. Dear Mum and Dad,
Jack and I are having a GREat time. Two days ago we were in Cardigan Bay with real dolphins, and a baby dolphin, too! I was really excited. We were in the boat with Jenny for six hours, but we weren't tired because it was interesting. Was it cold? Yes, it was, but now I've got eighty fantastic photographs of dolphins!
Where were we yesterday? Oh, yes. The ship was at Anglesey. It was Richard's birthday so yesterday evening there was a party in a restaurant. It was good fun—maybe because Patrick wasn't there. He was ill in bed.
At six o'clock this morning the ship arrived at Flint, and there was a bus to Chester. Now we're in a camp near Chester. We're having a survival weekend. We're checking our tents and equipment at the moment—except for Jack. He's asleep.
Jenny's calling me. It's time to go.
Lots of love.
Helen
