(i) Dad said 'Fall?' when Mum showed concern that he may fall while climbing the tree. He said it scornfully making fun of Mum'* concern.
(ii) Dad said 'Never mind' when he fell from the ladder as it slipped, during the first attempt to rescue the cat. He said so to clarify that everything was alright and he was okay and wanted to try again.
(iii) Dad said 'Funny joke' when Mum warned him about falling again. He said it boastfully feeling quite over confident of being successful in his Plan B of rescuing the cat.
(iv) Dad said 'Rubbish' when Mum asked him to stop trying again for the that he may break his neck, after his Plan B **. He said so because he thought that his Plan C will work and he will climb the tree easily and if he gave up, it might ruin his reputation.
