 You know, you really need to know somebody for at least a year, I think a couple of years, before you can really, really claim to understand them. And even then, I've talked to people who've had breakups. You know, people change. They've been with someone for 20 years, and they honestly and sincerely feel like, I don't know this man or woman anymore. Something has changed. And it doesn't have to be anything radical.
