I often do plan the evenings meal, but if I do that...I tend to have a preference for what we eat that night. HAVING to do that every night though gets very old. So when I give him a choice, or asking for a preference or an opinion...I'm really wanting him to help me out.
The rule you spoke of though is common in families...when it comes to the children and dinner time, I know it was in mine. But I would never presume to apply that rule to my husband.
