真正的朋友是異體同心。 ----亞裏士多德
Friendship with a man is friendship with his virtue. -----Mencius
友者也，友其德也。 -----孟子
There is no man that impart his joys to his friends, but that he joy the more; and no man that impart his griefs
to his friends, but he grieve the less. ----Bacon
與朋友分享歡樂者，無不歡樂倍增；與朋友分享悲傷者，無不悲傷減半。 ----培根
