If you could have your closest family members as neighbours, would you take up that option?

That would be your closest living relatives, whoever they may be. I wouldn’t at all, I mean yeah it may have some benefits, but these would be outweighed by the inevitable pitfalls. As it happens my Mum lives not two miles away, my brothers not much more than that & for me that works out just fine. Close enough to maintain regular contact, yet far enough away to not feel smothered. They do tend to interfere on occasion do mothers, with the best will in the world of course….bless em.
