Merci Hélène et Alexandra pour vos conseils.

I have so many favorite songs and artists, but if I must choose one...Juanes, "Para Tu Amor".

talking about a friend

One of my best friends is Marcello. I have known him since the first year of high school, where in Cagliari, where we were classmates for 5 years.
Marcello is 170 cm tall, well built, with a slightly dark skin tone, and has long black hair that he sometimes he lets grown up down to his shoulders. Because of this reason, our group of friends used to kidding on him (used to "tease" him...this is a better word) by saying that he looked like an Indian.
Although he has never received good marks at school, he has always shown an uncommon passion for writing articles. This skill, together with a fine inventiveness and a funny irreverent irony, brought brings together his ability to create incredible and amazing stories about me and each friend of ours, us that I take care like a (greatly/earnestly...these are enriching words that you can add to your essay) treasure.
But what I appreciate more in Marcello is the sincerity, and his being able to minimize problems and living with them without too much anxiety.
We share some interests such as soccer/football, travelling, and watching movies. Besides Additionally, Marcello likes still writing pieces about politics, and collecting patches and plates with the emblem of the cities he has visited.
If I compared my character( "personality" is a better word for this instance) and the  "to" or "with" marcello's one, I would say that we have a little in common, but this is what makes our friendship so "great" or "marvellous/marvelous" the good and marvellous in this friendship. I hope that we'll keep it, despite the time, the distance, the work....

**note**

marvellous can also be spelled marvelous for those of you who may be corrected byEnglish or American  editors

Computer games

Do you like computer games? I don't. But my husband is addicated to them. Before, he was addicted to Counter Strike, but now he is addicated to the World of Warcraft. He even can play the computer games for almost a whole an entire day, with the exception of except for eating, and using the toilet. I always felt get so bored about with this (or you can replace this with... "I find this so boring"). In my opinion, playing computer games are a waste of time.  It's bad for the eyesight, and it makes people sit in front of the computer for so such a long time, that they don't have time to do exercise. In the long run, their health will be badly ("adversly"...is a better word to use) affected. It's harmful to people, especially to children. I feel that most of the computer games are full of violence and that children would copy the games and become violent. So, the parents should manage their times in playing computer games. And As for the adults, they should also schedule their times and don't not play for too long.

Ex: playing computer games are...it becomes plural because you are speaking of more than one game; if you were only speaking of only one, than it would have been written: playing a computer game is

I also placed a comma (,) between eating and using the toilet since they are two separate actions. :-)

"I feel that..." because this is your opinion and not a fact.

I moved your sentence " It's harmful to people, especially to children" to help you support your argument
