Friendship is a union of spirits, a marriage of hearts, and the bond thereof virtue.

Penn.

Friendship that makes the least noise is very often the most useful; for which reason I should prefer a prudent friend to a zealous one.

Addison.

* * * * *

Friendship, like love, is but a name
Unless to one you stint the flame.
The child, whom many fathers share,
Hath seldom known a father's care.
'Tis thus in friendships; who depends
On many, rarely finds a friend.

Gay.

Friend is a word of royal tone;
Friend is a poem all alone.
