I see lots of posts about what I'd consider to be unreasonable behaviour in a family home (eg a recent one about cooking at all hours of the day and night, even when someone else is using the kitchen to prepare a family meal) and the responses seem to almost unanimously take the side of the young adult, saying that you can't restrict when a grown up cooks or whatever else it is they want to do. But how do you manage these dynamics? My feeling is that if a young person wishes to remain in the family home post adulthood, benefitting from either low or no rent and bills, they should be prepared to conform to the infrastructures in place to support family life. I think these infrastructures will be different for every home. I also think that those infrastructures will be different depending upon whether the household is uniquely made up of adults or whether younger children are still part of the household. Whilst young people aged over 18 are legally adults, I don't think they can claim all the rights of adulthood whilst also neglecting to understand that adults have responsibilities in terms of how they conduct themselves. Also is there a difference between 18 and non-contributing in any way and, say, 23 and making a decent contribution to the family? I would say that there is a difference but that until an adult is able to live totally independently, they should expect to be subject to some ground rules. They certainly would be if they went to be a lodger elsewhere.
As said already, I think that the infrastructures will be different for every family in terms of what feels acceptable or unacceptable but does anyone here have any "hard lines" - as in, this isn't acceptable in our family home and if you want to pursue it, you must live elsewhere? What do you do if your young adult won't comply with house rules but also can't move out yet? I'm finding this to be very difficult territory.
