Oil! by Upton Sinclair

Dad didn't get well as quickly as they had hoped. Apparently the cold damp darkness of London was not good for him, so Bunny took him to Paris. Bertie relented, and met them at the station; even her husband risked his diplomatic career, and everything was polite and friendly for a few hours. But then the brother and sister got to arguing; Bertie wanted Bunny not to investigate the Socialist movement of France, at least, and Bunny said he had already promised Rachel an article about it. There was a "youth" paper here that was on their exchange list, and there was to be a Socialist meeting that very week which Bunny was going to attend. Bertie said that settled it, he would never meet the Prince de This and the Duchesse de That, and Bunny was so ignorant, he didn't know what he was missing.

Paris was wet and cold also, and Dad had a cough, and sat around in a hotel lobby and was so forlorn it made your heart ache. He would let you drive him around, and would look at public buildings -- yes, it was very fine, a beautiful city; people had been working on it a long while, we hadn't had time to get anything so good at home. But all the while you could see that Dad didn't really care about it; he didn't like this strange people with their jabber, the men looked like popinjays and the women immoral, and people were always trying to pass off lead money on you, and the food had fancy fixings so you couldn't tell what it tasted like, and why in the world Americans wanted to come chasing over here was beyond Dad's power to imagine.
