George MacDonald

Your friend has never really loved you, never quite trusted you, who lightly lets himself think that you have drifted away from him.

Bishop Thorold

There are three faithful friends—an old wife, an old dog, and ready money.

Benjamin Franklin

Should auld acquaintance be forgot,
And never brought to mind?
Should auld acquaintance be forgot,
And days o' lang syne?

Burns

There is no treasure the which may be compared unto a faithful friend;
Gold soone decayeth, and worldly wealth consumeth and wasteth in the winde:
But love once planted in a perfect and pure minde endureth weale or woe;
The frownes of fortune, come they never so unkinde, cannot the same overthrowe.

Roxburghe Ballads
