What is the difference between intelligence and common sense?

I am explaining my view by an example, please read it.

An engineer in a car manufacturing company designs a world class car.

The owner is impressed with the outcome and praised him a lot.

While trying to bring out the car from the manufacturing area to the office they realised that the car is few inches taller than the entrance.

The engineer felt bad that he didn't noticed this one before creating the car.

The owner was amazed on how to take it outside of the manufacturing area.

The painter said that they can bring out the car and there will be few scratches on top of the car that he will do the tinkering later on.

The engineer said that they can break the entrance and after taking the car out, they can cement it.

The owner was not convinced with any ideas and felt like it is a bad sign to break or scratch.

A watchman was watching all these... and slowly approached the owner.

He wanted to give an idea if they have no problem.

They thought what this guy would tell them that the experts could not give.

Watchman said that The car is only few inches taller than the entrance so if they release the AIR in the tyre, the height of the car will be adjusted and can be easily taken out.

Everyone clapped!

Apparently, designing a world class car is surely a matter of intelligence but briging it out from factory as in above said circumstances is surely a matter of common sense.

Think simple...

Do simple...

& Live simple.
