Extraordinary creature! So close a friend, and yet so remote.
Books are the quietest and most constant of friends; they are the most accessible and wisest of counselors, and the most patient of teachers.
Be slow in chusing a Friend, slower in changing.
A man cannot be said to succeed in this life who does not satisfy one friend.
As a friend, as a friend as a known enemy.[Also know as:]A friend is nothing but a known enemy.
A false Friend and a Shadow, attend only while the Sun shines.
