To forgive is not to forget, nor remit, but let it go; to be lonely is not because you have no friends, but no one is living in your heart.
Anyone can catch your eye, but it takes someone special to catch your heart.
Regret for the things we did can be tempered by time; it is regret for the things we did not do that is inconsolable.
If two past lovers can remain friends, it's either they were never in love or they still are.
