Good deal DJ, Sounds like the easiest way out of the pickle for now. My Mom is 82 and doesn't walk all that well anymore. Since I have a big house, she's here with me and has a downstairs bedroom. It was a no brainer for me. She raised 5 of us pretty much by herself and I don't mind the role reversal.
My Mom is in her late 80's now and wouldn't think about living with anyone - I've tried, several times... she's doing very well, still drives although now only locally. Keeps herself full of projects and I can hardly call her and find her home -during the day... Gotta love it! My older brother was off at a party one night and somehow the subject of parents came up and my brother said he could call his mother right then and she'd still be up. Everybody got a huge gafaw out of that with lots of "Oh yea, right, sure you could".. so he called her, it was about 3:30 in the morning, she picked up the phone on the second or third ring complaining it took her too long to get to the phone 'cause she was in the middle of a project and couldn't get to the phone right away... Those two then chatted for awhile so that the rest of the folk at the party could pick themselves back up from falling on the floor...
