Copy to Comrades Kamenev and Zinoviev

Dear Comrade Stalin:

You have been so rude as to summon my wife to the telephone and use bad language. Although she had told   you that she was prepared to forget this, the fact nevertheless became known through her to Zinoviev and Kamenev. I have no intention of forgetting so easily what has been done against me, and it goes without saying that what has been done against my wife I consider having been done against me as well. I ask you, therefore, to think it over whether you are prepared to withdraw what you have said and to make your apologies, or whether you prefer that relations between us should be broken off.[1]

Respectfully yours,
Lenin
