Hi Butterfly!

The child goes off to college sometime after the age of 18 and they stay outside of the house until one or both of the parents have passed away.

When one parent passes away, you get the option to start a new generation in the family tree which will force the remaining parent to move out as you choose one of the children to take over the home. You can wait until everyone has passed away before moving on to a new generation if you prefer.

They don't come back for visits from the college, all they will do is send off an e-mail now and then that your other peeps can read.

Best of luck with your family!
