If a man liked his friends’ painting or writing, I thought it was probably like those people who like their families, and it was not polite to criticize them. Sometimes you can go quite a long time before you criticize families, your own or those by marriage, but it is easier with bad painters because they do not do terrible things and make intimate harm as families can do. With bad painters all you need to do is not look at them. But even when you have learned not to look at families nor listen to them and have learned not to answer letters, families have many ways of being dangerous.
