《孔子家语·终记解》
子游说： 我听老师说过，对待朋友的丧事，在家时系麻带，出去则不系。自己的尊辈去世了，即使系着麻带出去也是可以的。 
子游曰： 吾闻诸夫子，丧朋友，居则绖，出则否；丧所尊，虽绖而出，可也。 
Zi You said: I heard the teacher say that when treating the funeral of a friend, I will wear hemp at home, but I will not wear it when I go out. When my own elders die, I can wear hemp to go out.
