Mary suggested going for a drink.
Jane refused and explained that she had promised to help her mum prepare the party, her dad was fifty the following day.
Mary was surprised and said that he looked much younger.She inquired if he did any sports.
Jane explained that he used to play tennis but he had to stop because of his elbow. Jane invited Mary to come to the party if she liked and added that it started at 6.
Mary thanked and accepted the invitation.She wondered if she could offer her help in the preparations.
Jane agreed and said that there would be over sixty people so they really needed a lot of help.
Mary advised that they should use a catering company,they could prepare the food and clean up afterwards.
Jane admitted that it was a good idea, but her mum wouldn't hear of anyone except her preparing her dad's birthday cake.
