just as Vincent's Picks described. 

My wife and I both wasted a lot of time as teens.  My teenage boys waste a lot of time, as well.  I am not proud of that, but my daughter's time wasting is much more isolated, in her room, door closed.  Sometimes my boys will grab their Nintendo Switch and do the same, but when I ask them to come to the living room so we can at least enjoy their company, they come on down.  My daughter? No. The only way I can get her to leave her room is if I go hang out in her room. 😑

That's what is concerning.
