L is for Love
Love is like a building.
Before marriage, the relationship is like the construction of a new building. During this stage, should there be any fundamental flaw, serious problems may arise after the building is completed, for eg. a shaky or slanting building.

During construction, there will always be new problems cropping up like soil issues, lack of materials, costs exceeding budget, site accidents, etc – these are like lovers’ tiffs which occur once a while, some more frequent or ferocious than others. Some tiffs can be resolved, like construction issues, but some can simply not be resolved and the project is called off.
If the relationship breaks down before marriage, the half constructed building is left abandoned. In future, if things patches up, the construction picks up again and there is a chance that the building may see the light of the day.
Marriage is like a completed building. In the honeymoon stage, things are just sweet. Similarly, a building gets new furnishing, everything looks new and at its best (probably this would be the best it will look in the entire lifespan of the building). 
The completion of building does not mean that problems will end, it just mark the start of a new set of problems, for eg. burst pipes, water leakage, etc. In a marriage, new set of problems arises – from living together, finances, in-laws, children, etc. It takes effort to maintain and renew the marriage, just like any building. Badly maintained buildings just look dead while well maintained buildings maintain its lustre – the amount of effort put in = state of the building/marriage.
Renewal of marriage wows is akin to a building undergoing refurbishment and everything looks good and new again but the structure remains unchanged.
Should there be fundamental flaw not addressed in the initial stage , it may come back and haunt the marriage. In the case of the building, fundamental flaw could lead to building safety issues, etc. Some flaws could still be repaired, in more severe ones, it may be technically impossible to repair – it could even lead to the collapse of the building.
When a marriage breaks down, both parties leave the relationship – some amicably, some with bitterness. In the case of the building, the occupants leave the building and the building is left in an abandoned state or torn down by the authorities.
Do you think this is a good analogy? I am going to lobby for MCYS and BCA to merge….since they are duplicating work and wasting taxpayers’ money.
