Dear John, Thank you for your invitation to dinner at your home tomorrow evening.Going online has become more and more popular because of its convenience.In many people's view,knowing how to go online is a kind of skill and the quick and large amount of information will help people a lot in nearly all areas.But nothing is perfect.Spending too much time on line will be harmful for people's health and makes people do less exercise and have less time to talk with others face to face.What's more,depending on the computer too much,people's creativity will be lacked because they always get thoughts from others. In my opinion,indeed ,going online helps us a lot and sometimes we have to depend on it but time shouldn't be too long and we must control ourselves when we realize we spend a long time on it.If we can do this,going online is a great way to develop the world. I wish you have a good time.
