Sad for lost opportunities. Angry at wasted time. Grieving for every missed chance to be nurturing and loving that was squandered for reasons that don't look all that important now. The days when I could have cooked that favorite dish but didn't. The lonesome nights when I could have been comforting but was unavailable. Grains of sand. Purgatory in an hourglass vault.
Add these things to my list of regrets.
