Part of my bedtime routine when I was a child was to say my prayers with my parents and then confess any wrong I had done during the day. Sometimes I made my parents sad, and myself, too, but my confessions were always followed by immediate forgiveness, by assurances of love, the love of my parents, the love of God. I am grateful for the teaching given me by my parents, because it grounded me in an awareness of God's all-embracing love.
Compassion literally means to feel with, to suffer with. Everyone is capable of compassion, and yet everyone tends to avoid it because it's uncomfortable. And the avoidance produces psychic numbing -- resistance to experiencing our pain for the world and other beings.
