I like the Channel 4 series Obsessive Compulsive Cleaners. It teams people who tend towards Obsessive Compulsive Disorder behaviours with hoarders and people who either don't know how to, or can't be bothered to, clean their home.
These people are polar opposites and the premise for the show is that these two different people can enjoy a brief symbiotic relationship; the obsessive learns that letting go a little isn't disastrous and the hoarder learns that it is possible to de-clutter and clean house.
The pairings aren't always successful but often they are with both participants gaining from the experience.
It made me wonder whether there are other unusual bedfellows that might benefit from exposure to an opposite. The only one I could conjure was the mixture of an agoraphobic and claustrophobic. I wonder if there are others.
