TYPE 2 Person : The person is THE BUS itself. Maybe one passenger or more get in. The bus travels from one source to destination enjoying every single passenger ride on it. Taking this seriously if the bus takes more passengers than it actually should causing an overload, it will eventually breakdown half way. The bus not being a small vehicle keeps carrying multiple passengers ruining itself due to wear and tear.
TYPE 4 Person : The TICKET CHECKER who is controlling who can get in the bus and who cannot. The poor bus might not want an overload or just rely on the ticket checker to check that the right people are riding it with the right permissions (tickets). If the ticket checker is corrupt or stupid... the bus will break down.
TYPE 5 Person : THE ILLEGAL PASSENGER is a kind of person who will get into the bus just for a free ride. The bus is so much used to multiple passengers and so is the conductor who might miss on even checking on a passenger traveling for free. This kind of passenger has the least to loose. It has a habit of climbing into any bus with a particular destination in mind. He enjoys the ride and gets away clean.
If a relational algorithm is created from the above entities, one will find that all these roles are habitual. The role of the bus and the passenger itself are worst. Replace a bus with a vehicle that a passenger is trying to buy. A passenger might be buying a new vehicle not knowing that it is used, at the same time the passenger might be buying a used vehicle not knowing how many times it has been used for real. In the worst case the passenger might not be aware that this vehicle is jinxed to change its owners too soon. In the vehicles case the vehicle might find a new buyer wealthy and nice hoping for royal life, but the buyer might be renting out the vehicles! The vehicle might not be maintained or attended well if the buyer has too many of them. A buyer might abuse the used vehicle if it fails to perform as much as the seller had promised him it would, or maybe it fails to perform as much as it did in the trial ride.
The public transport vehicles represent people who are known to keep only few people like driver and ticket checker on board all the time while changing the passengers habitually all the time. They might be circulating the people in a particular relation many times and still not feeling anything wrong or messy about it. They are so much used to the fact that they are confident to carry next passenger till whatever destination as long as they can. The passengers who board or buy wrong vehicles are generally emotional fools who go more on instincts and less on logic and suffer equally boarding or buying a wrong vehicle.
To end the blog finally to make the friends of my spiritual network happy - ITS FATE! hahaha but still I suggest you all to identify with the above examples and then correct yourself or play safe!
