Viewing a vehicle's head lamp at a distance in the night, all you will see is a starlike shape, but on getting close, you will see the real light source.
Marriage may shine like a star, but when you get closer, you will notice that all that glitters is not gold.
There is no perfect marriage in the sense that both spouses are imperfect; they came from different backgrounds, perhaps language, tribe, religion, and education.
