[quote=Diabolicalrhapsody] "Umm...not to sound dumb. But you see, the main problem with me and I think with Kat is that whatever we have learned is more from experience than practice or process. So when you hand us a ten dollar note and say it is a twenty dollar one we know that we need ten more to meet your actual claim. Throughout our lives we have had so many such experiences that these calculations are more instinct than anything. So I simply can't narrate how I can calculate whatever I could." Py said in an earnest tone. [/quote] "You can tell notes apart?" Katherin asked in surprise. She couldn't. They all felt the same to her. She could tell coins apart because they were different sizes but the paper money was all the same to her. "I have to trust someone to tell me which note I have. Its one if the things I'm hoping to learn."
