One must know that for everything there is a time, and when this is not considered one makes a mistake. When one wakens a person at two o'clock at night his sleep is broken; he ought to sleep all night, it was necessary for him. Not knowing this, people very often try to wake a person up, their wife, husband, friend or relation, their child or father. They are very anxious to awaken the other; often they feel too lonely and think, "This person is close to me, he should be awakened too." It is the same with the one who smokes or drinks: he likes others to have the same experience, just as it is too dull for a person in a cheerful mood if the other one is so dull that he cannot laugh and see the joke.
