I think the right way of using cell phone is do not speak louder in the train or bus.
We have to care about other people in the bus or train when using a cell phone.
And also, we do not have to use cell phone near by the priority seat.
Using cell phone is not good for body.
There are some differences between ages how to use cell phone in public.
Young people are more likely to cell phone rather than old people.
Some old people hate to use cell phone and they think its annoying.
Therefore, people should not use cell phone in selfish way like talk in the train.
That is important for all generation people to spend life confortable.
