It felt comfortable to be in a country where it is so simple to make people happy. … Everything is on such a clear financial basis in France. It is the simplest country to live in. No one makes things complicated by becoming your friend for any obscure reason. If you want people to like you, you only have to spend a little money. I spent a little money and the waiter liked me. … He would be glad to see me back. I would dine there again some time and he would be glad to see me, and could want me at his table. It would be a sincere liking because it would have a sound basis.The Sun Also Rises p. 233
