Okay so my DB and DSIL are looking for a new house to rent in my area. Literally this morning, the one right next door to me has gone up for rent! It fits 80-90% of my DB criteria and as a laugh we, as a family, joked about him moving there. When I got home I realised it just wouldn't work (not that he is seriously considering it), but I just don't think the dynamic would work, its far too close.
It got me thinking though, could you live next door to a sibling? We are both married, both have 2 DC of similar ages for context. Would you be happy if a sibling moved right next door?
YABU - Sounds like the dream team, can all help with DC and enjoy each others company.
YANBU - My version of hell, me and my siblings vary hugely in personality and it wouldn't work.
