Best way from here....

Best way from here....

Several years ago my aging Parents stayed with my Brother and sister-in-law for a few months.  Was stressful for all parties at that time.

 Several years later Mom has died and Brother tells Dad hs is moving to their place again.  I asked at that time if they could deal, Dad is messy in the kitchen; was assured all would be well.  Brother had offered to hire a cleaning service but never did. My place is very small and if Dad lived here he would be sleeping in the living room.  At times he has asked to move in, but he gets why that isn't a great idea.

Now; sister-in-law is stressed out from all the extra work and Brother keeps telling Dad about the big burden he is on their family.  Brother told him if there was any other way he wouldn't be in their house.  Mind you Dad still drives, does his own laundry, and mostly takes care of himself at 88 years of age. 

Dad tired of all the silly post it notes around the place and the burden comments went asking at a senior center for a room to rent.  Dad has put a deposit on a room in someone house; and wants me to help explain it to Brother and sister-in-law.

I'm with Dad on this and suspect Brother and Sister-in-law will be unglued that he just went out and did this.  any ideas on helping our family?
