As an adult, have you ever lived under the same roof with your adult sibling(s) for 6 months or more? If so, how did it go?

Four months was the most.  Thank goodness for it because I could not have managed after knee replacement without help.  Then there were lots of complications and more hospitalization.  So glad all of that is behind me.   

I have. We are both still alive. That's how it went. :-)

no, once i went away to college i never went home again
