one grain can feed all!!!

our household help has started helping another household in the morning. so she rushes through her work in my house glancing at the clock every 2 mins. she makes some 5 rotis every morning. one day i asked her to make 2 more when she was almost done with the last. she stated that as impossible as her dough was over for the day and my demand would require her to spend more time making some afresh. and reprimanded me for not telling her earlier, cos then she could have made the 2 more from the same dough by reducing the size. her cheek amazed me and i couldnt help laughing out loud. i told her i wasnt asking for a skilful display of her reproportioning scarce food resources but simply more cooked food for more mouths!
