Maxim Gorky said this quote
“ the mother again remarked the simplicity and calmness of their relation to each other. it was hard for her to get used to it. no kissing, no affictionate words passed between them but they behaved so sincerely, so amicably and so solicitously toward each other. in the life she had been accustomed to, people kissed a great deal and uttered many sentimental words, but always bit at one another like hungry dogs. ”
