Love is whatever you can still betray. Betrayal can only happen if you love. - John le Carré

Smiley himself was one of those solitaires who seem to have come into the world fully educated at the age of eighteen. Obscurity was his nature, as well as his profession. The byways of espionage are not populated by the brash and colourful adventurers of fiction. A man who, like Smiley, has lived and worked for years among his country's enemies learns only one prayer: that he may never, never be noticed. Assimilation is his highest aim, he learns to love the crowds who pass him in the street without a glance; he clings to them for his anonimity and his safety. His fear makes him servile - he could embrace the shoppers who jostle him in their impatience, and force him from the pavement. He could adore the officials, the police, the bus conductors, for the terse indifference of their attitudes. (ch. 9)

Yes, dear Father. But has it ever occurred to you that by controlling [your feelings] you destroy them? How many times can we say sorry before we don't feel sorry anymore?

I should have guessed you’d never have the guts to do your own dirty work, Fiedler. It’s typical of your rotten little half-country and your squalid little Service that you get big uncle to do your pimping for you. You are not a country at all, you’re not a government, you’re a fifth-rate dictatorship of political neurotics.
