Is it normal for teens stay in thier room?

Ah do I miss the days when they were young. So easy to please, happy for just about anything you do for them, always inquisitive, and always a joy to be around. But then one day something happens, they become teenagers and suddenly they are aliens. I never see my teens anymore, they come to the kitchen and bathroom, but other than that they are in their rooms. I have tried to change the behavior, but it is too much of a struggle, and I feel that I am pushing them further away.
Is this something they just grow out of, or something I should be concerned about?

I have a different opinion
