Platonic friendship-the interval between the introduction and the first kiss.
Enough of anything is plenty, but plenty to some people is never enough.
Never expect too much from a friend and you will never want for one.
A friend is one who withholds judgment no matter how long you have his unanswered letter.
It is wise to be sure, but otherwise to be too sure.
Riches may not bring happiness, but neither does poverty.
