I used to travel by bus to got to the office. I got some of the new friends on that bus. Because of us, the bus is very naughty mode. In addition to this, the bus carries almost regular passengers. So, almost everyone knows everyone in that bus.
Some days, some of the friends used to be late to their bus stop, this cause to be missing their buses on that day. So those days, the bus is very silent and not an active mode.
If someone presence is missing in any group reveals that the person is deserved for the real value of his love with other people.
