A Chasidishe boy met a girl for their one and only meeting before deciding whether to get married. Since the boy had never spoken to a girl before he was too shell shocked to say a single word. So his father went to ask the Vizhnitzer Rebbe if he can meet her again. The Rebbe asked why. The father said that he doesn't know the girl at all. He didn't say a word the whole time.
The Rebbe said "I am married to my Rebbetzin for 45 years and I still don't know her. He expects to get to know her in 5 minutes?"
