"Late you come, yet you do come!... You should have recognized the beneficial power of criticism when we were in the opposition. Back then, you had not yet been confronted with these words; back then our press was verboten and verboten and again verboten; our assemblies were banned; we were not allowed to speak, and I was not allowed to speak -- and that went on for years! And now you say criticism is beneficial!"
