On my return trip the plane was delayed for about six hours. We just SAT there. I got up to dance but nobody wanted to join.. So we just sat.
It turns out that there was a problem with the motor. So I thought - better we find the problem here on terra firma [firm ground - picked that Latinism up from Rav Soloveitchik :-)] than finding it 30,ooo feet over the Atlantic.
This true story is of course a metaphor for marriage. Sometimes a person is dating and they discover a serious problem in the other person that compels him/her to break up. It hurts. But better before marriage than afterwards when you are 30,000 feet over the Atlantic, so to speak.
