"Love is always patient and kind. It is never jealous. Love is never boastful or conceited. It is never rude or selfish. It does not take offense and is not resentful. Love takes no pleasure in other people's sins but delights in the truth; it is always ready to excuse, to trust, to hope, and to endure whatever comes. Love does not come to an end." -quoted in A Walk to Remember
The first time I heard this, my automatic response was, "Love must not be human."
