During Gerry's tennis lesson, Madeleine and Ella came to the adjoining court with their Mini Club for a mini-tennis session. Jane and I stayed to watch them. It chokes me remembering how my heart soared with pride in Madeleine that morning. She was so happy and obviously enjoying herself. Standing there listening intently to
Cat's instructions, she looked so gorgeous in her little T.shirt and shorts, pink hat, ankle socks and new holiday sandals, that I ran back to our apartment for my camera to record the occasion. One of my photographs is known around the world now: a smiling Madeleine clutching armfuls of tennis balls. At the end of their session, the children had been asked to run around the court and pick up as many balls as they could. Madeleine had done really well and was very pleased with herself. Gerry loves that picture.
So, Jane was there too, so was the Nanny, and the children were asked to run around the court and pick up the tennis balls. So no one has come forward to say 'nope that wasn't taken at the tennis court in Portugal' have they?
