Satisfaction.

'When I'm watchin' my TV
And a man comes on and tells me
How white my shirts can be
But he can't be a man 'cause he doesn't smoke
The same cigarrettes as me.'

- 'Satisfaction' - Jagger/Richards

You want to resolve complaints to the satisfaction of the complainant?

You want someone else's happiness to be a measure of your decisions?

Good luck.
