DISDad Challenge
This may seem easy, but I assure you it is not.
This has to be kept strictly confidential until you execute.
Tonight, when you go to bed... switch sides with DW. Just lie down on her side, and go to bed.
When she asks you what you're doing, just tell her you want to switch things up, and she doesn't own the bed, squatters rights, etc...
You win, if you successfully make it through the night with all body parts in tact, and very minimal bruises.
Report back tomorrow morning.
