Crime and Punishment, by Dostoyevsky

I'm always sitting and so glad to be moving about for five minutes...I suffer from my sedentary life...I always intend to join a gymnasium; they say that officials of all ranks, even Privy Councillors, may be seen skipping gaily there; there you have it, modern science...yes, yes....But as for my duties here, inquiries and all such formalities...you mentioned inquiries yourself just now... I assure you these interrogations are sometimes more embarrassing for the interrogator than for the interrogated....You made the observation yourself just now very aptly and wittily.†
