About the not rinsing thing: something interesting.
When I first moved to the UK, I lived with my MIL, FIL, SIL, BIL and husband.
People who rinsed the dishes: MIL, Husband, Me
People who did not: FIL, SIL
Uncertain: BIL
My MIL was so grossed out at the fact that my FIL did not rinse the dishes! And FIL was like why should I??? This tickled me so much.
My husband, BIL, and SIL are awful dish washers, but they had absolutely, positively zero chores growing up.
