How Regret Can Help Us Find Meaning and Connectedness

How can my regret help me find a sense of meaning? I'll give you an anecdote. When she was a kid, her grandparents came from Indiana and stayed with her for a couple of months every year in Arizona. She didn't want it; thought they were butt-inskies. A few years ago, 20-something Abby said, oh my God, I totally regret that I acted that way. And so she started doing something where she began recording her father's stories systematically hearing her parents' stories. So she would have a sense of connection with him that she lacked with her grandparents.
