The son-in-law interrupted. "I hate factories. I can't stand the noise."
"I see," replied the father-in-law. "Well then you'll work in the office and take charge of some of the operations."
"I hate office work," said the son-on-law. "I can't stand being stuck behind a desk all day."

"Easy," said the young man. "Buy me out."
