It sounds like discrimination to me, like creating a ghetto to isolate people that other people don't want to get involved with. In other countries they used to create hospitals to black people (as if there were any kind of black people), hospitals to white people (as if there were any kind of white people), schools to black children, schools to white children, remember? Is this option any less wrong? Remember: couples are just that: couples. And old folks are just that: old folks, who deserve to be loved and respected. One day, any one of us will be, if we're lucky to get there. Respect them. Being segregated in a home is bad enough. Shame.
