Yes, we have unwritten rules.
1. I'm the only one who drives, all controls, including the radio are under MY purview. Hubby may not touch;
2. He does the dishes. I cook.
3. he will not do laundry. It's the chore he hates.
4. He has to have his own big bag of chips. He doesn't want to share. He gets his own and I get mine.
5. I buy the groceries and he can't come (we spend less money that way)
6. His painting studio is off limits. I don't clean it until he requests it. He has some sort of chaos in there that works for him.
I could go on, but maybe I'll save the rest for a story of my own. ;)
