Regrets

I've done several things over the course of my life that were so bad that "I'm sorry," couldn't fix it. There are times where my dad has said, "Sorry doesn't cut it." One time it was winter and my brother wanted me to pick him up at the college. I got mixed up and waited in the wrong parking lot, in the garage, while he shivered outside at some other parking lot. My parents eventually came by to help him, but I couldn't just say sorry and make up for that.
Also, a long time ago, I made a joking comment about my mom's weight and she's still on a dieting regimen.
