It's good to massage your fiancee.
John's fiancee Vanessa works in heels all day and often comes home with sore feet, while he works construction and comes home with a sore back.
John wants to relax after work.
John tells Vanessa he'll massage her feet if she massages his back afterwards.
Vanessa asks John for a foot massage, and he denies her so that he can take a nap.
John and Vanessa benefit from a win-win situation and are able to relax after their massages.
Vanessa is left with no relief and resents John for denying her.
