I dislike severely when my Russian friends or family members look down on someone for having gaps in what they consider "general knowledge".
"You've never read Hemingway's Man and the Sea? You never opened The Catcher in the Rye? How can you call yourself an educated person?"
"Well, you don't know all the parts of RNA polymerase. You couldn't tell a good Japanese woodblock print from a bad one. Not to mention your complete ignorance in mating behavior of kakapo parrots."
"How can you even compare?.. Hemingway!.."
