A：Hey, there's Leo. I wonder why he's walking arm in arm with that young woman.
B：It's as plain as the nose on your face. They're dating each other.
A：You're pulling my leg! She must be thirty years younger than Leo. Talk about robbing the cradle!
B：Well, you can bet this relationship's going to be a flash in the pan.
A：It must have been love at first sight because I know he didn't have a girlfriend last week.
B：I think you are absolutely right. Actually, my father proposed to my mother after knowing her only two weeks. They got married a month later.
