The other wiki has a description of this. If that's what you want, go there and check it out.
No! Don't leave me here by myself! I can't bear not having you around; I'll just miss you so much.
Parents are involved in their children's lives (well, good parents are). Parents love and support their children (well, good parents do). When children move out of the home and on to college, parents miss them terribly (well, you get where this is going). It's more than missing the child, there's a sense that the parent has lost something important in her life (it's somewhat more prevalent in women). Something similar happens when the child gets married.
Contrast Basement-Dweller, where a grown-up child overstays his welcome, although it doesn't always guarantee this trope won't happen when the day finally comes.
