Would you put your parents in an elderly institution when they grow old?

I'm fairly sure that my parents don't want me to have to look after them when they get old. I wouldn't want my own kids to have to take me in when I get old. It seems noble and right to do it, but I have witnessed too much bitterness and resentment due to parents moving in with their children to want to have to go through that. In a more extreme case, we had to place my father-in-law in a special home due to the fact that he had alzheimer's disease. This was incredibly hard for my wife and even hard for my mother-in-law to do. He was only 65 when in was placed in a home, but is condition was so bad it was impossible for us to take care of him. He passed away a few years ago and my wife and her mom still feel guilt over placing him in a home but I saw the stress and the emotional drain it had on them to try and keep him at home. For my own children, I plan on making sure that they know that they don't need to take me into their home when the time comes.

When that time comes, I will have no choice but to put my mother in a home. She has mental and emotional issues that are not healthy and I refuse to bear her abusive nature. Parents sometimes forget that the very people you control without mercy, will probably be choosing your nursing home when the time comes.
