“Lawyers make great mathematicians,” Mandy said, “because they like to follow rules.”

“Well,” Jamie replied, “there’s Descartes.”

“Descartes, who is famous for saying ‘I think, therefore I am’,” Mandy quoted, “he graduated from college where he studied law (apparently with little enthusiasm), before becoming a mathematician and inventing the Cartesian plane.”

“St Augustine, 500 years before Decartes, said ‘fallor ergo sum’ meaning – ‘I err therefore I am’,” Joe commented.

“But I think higher level mathematics is more an art than a science, which is the beauty of it,” Jamie replied, “an answer pages long to a single line question – now that is amazing.”

“Reminds me of college girls who, following a single line question, load their entire life story on you,” Joe replied.

“I think someone liiiiikes Joe,” Mandy said.
