Depending upon the circumstances, it can work out well for both the parents and the kid for the kids to stay longer at home than expected. We have a garage that we converted into a studio apt for our oldest son and his wife so they could stay there and save for a place of their own rather than making some landlord rich. I put in a mini kitchen, a bathroom and finished it off with some nice touches such as crown molding, track lighting and a french door. They have a nice new home now and so our youngest son has moved in and is doing the same thing. We enjoyed having them and hardly knew they were here most of the time.
Having said that, I think there should be a definite plan in place and a time limit if adult kids plan to stay on in the family home.
There was an elder and his family that attended our hall who had two very heavyset adult daughters that lived at home and Pioneered and were Nannies. One of the daughters used to bring the kids she watched, to the meetings and assemblies. At the last circuit assembly I attended she was once again hauled up on stage at 36 years of age, to talk about having taken a stand in high school by refusing an invitation from a "worldly" boy to go to the Prom.
Speaker: "Mindy...what advice would you give to our young ones who are being tempted to participate in school activities."
Mindy: "Well Brother Smith, I faced these temptations in high School. I was once asked to the senior prom by a worldly boy."
Brother: "How did you handle this situation Mindy?"
Mindy: " He was a nice boy but even so, I told him NO !!! He and the other kids respected me because I let my yes mean yes and my no mean no. "
It was pathetic to think of this young woman having turned down a simple invitation to do something fun 18 years previously and wound up still living in her childhood bedroom, pioneering and taking care of other peoples kids. There were smirks on the faces of the high school girls in front of us. I heard one of them whisper "it's so sad she never got married because she loves kids so much."
Time has a way of flying by and opportunities for personal growth are often missed when one takes the easy route and stays on it for too long.
