Technology

I often use many technology products. Especially,I use my cellphone everyday.
It has many functions.We are able to send massage , talk with others,take a photograph and so on.The cellphone is very convenient so it is necessary for me.

But I think that we should keep it's manner and rule.
We are able to many things by cellphone. Not only right things but also bad thing.
For example,we able to send harassment massage and mischief telephone.
Sometimes,its connect crime.

So I think that when we enjoy using technology ,we should take careful how to use.
