Do you have a cell phone?
Do you think children need a cell phone?
When I was a student, cell phones were very expensive. Young peple could not have cell phones.
And thirty five yeares ago(1970), the Japan world exposition was held in Osaka city. Big cell phones were displayed in Expo '70. (When we went to the expo Park to see the poster in which people carried their cell phones on their shoulder.)
Japanese could not believe that we would have cell phones in our future. But now even the children have cell phones.

In my opinion, children don't need cell phones. I know cell phones are uesful. If children get email, they can return it. That causes childeren to do bad things sometimes.

That's why children shouldn't have cell phones.

On the other hand, there are some pay phone in towns. And vicious crimes are increasing in Japan. Anyway I may not say such a thing. We parents make give cell phons which have GPS for protecting our children.
