I\'d like to go away for a holiday again soon. You must come and see us again one of these days. Let\'s all go and see Harry this weekend. I\'ve found something very strange. Come and have a look. I\'m afraid Mrs. Barnes is busy just now. Could you come back tomorrow morning? Do you know Africa? - No, I\'ve never been there. This is my first visit! I\'ll never forget that morning 20 years ago when I first saw Mrs. Newton. Jane, I\'d like you to meet Peter. Peter, this is my friend Jane.Who were those people you were with last night?
