I used to be really addicted. Now it's something i like and use a lot, and would find it hard to live without. Leisure but also work. And contact with family/friends.
I use internet since only 4 or 5 years and i used to say i didn't want internet at home. I said it was a danger for kids too. I didn't see what was interesting in it. I thought if you need to find something particular you can use your encyclopedia or go to the library, and for family and friends there is the phone ! etc etc etc ...
Now i work sometimes in computing and help friends and friends of friends of friends with their problems about pc's. lol and i've got two pc's at home, one i optimised and one i create myself
In fact i discovered something i really like, it sometimes take too much of my time as i help users on a forum too. But i like all about it.
