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.
