“The Offence” by Vladimir Nabokov.

‘The children went to the garden,’ said Anna Fyodorovna (Kozlova) when Putya with his sister strolling down through the chilly rooms smelt of pinks had appeared in verandah; there were about ten people sitting. Putya bowed and scraped his feet before each guest trying not to smack the hand of a man by mistake as it happened once. His sister put her palm down on the top of his head: it never occurred at home. Then she sat down in a wicker chair and cheered up extremely. At once everybody started talking.
