Not everyone that board at the same bus stop as you will alight at the same stop.Different people have different destination in mind. Those who start the journey with you seldom finish with you. Some choose to get off earlier, while some want to go all the way to the interchange. There will be those who board the wrong bus, and those who miss their stop. There are times where you travel alone, and also times where a group of people is accompanying you.
Life is like a bus journey; do you have your destination in mind already?
