When you overhear your husband on the phone with his parents telling them that they are wrong about something and you are right.
Not so sweet but kind of funny because haven't we all been there?
Your husband is talking about an old girlfriend. You ask if she is The One Who Got Away or The Bullet He Dodged. He replies, "Can't she be both?" But then exhales and says, "I'm so glad I married you."
PS I have one of those, too, a guy in grad school whom I am now convinced is a quasi-sociopath. Not a criminal, but completely lacking in conscience. But boy could he kiss.
