Dear brother,
In recent years, the world has witnessed a booming number of mobile phones. They are dramatically changing the way people contact to each other. It is apparent that mobile phones has had a profound influence on personal lives. However, not all the effects of them have been positive.
 it is true that people are now getting a number of advantages from mobiles, these communication technologies also have several negative impacts. Firstly, using cell phones too much will probably be harmful for human's health as it can increase the risk of brain cancer. In addition, children are spending a lot of their free time on using mobiles with the purpose of chatting or playing games. This is time consuming and affect negatively on their studies. Lacking of face-to-face communication is also the result of using mobiles. Instead of going out or dating, many people prefer to stay at home and use their cell phones to connect to others.
so, dear brother, i advice you to use your cell phone as little as possible.
give my regards to aunt and uncle

yours affectionately.

this was all i could think of........
