No one is perfect.
When we try to be perfect, we wind up feeling like a perennial failure and when we insist on perfection in our relationship we doom them from the start. Perfection is a fantasy (i guess sooo), a flight from reality, a fairy tale, albeit a beautiful one at times. Forgiveness, of ourselves and others, allow us to embrace our own or other people's imperfections, soo that we can release the "pain" and feel pleasure. So that we don't undermine our experience of joy
