It's a reasonable question to ask. Division of labor is certainly a major way a society improves both individual and societal efficiency. This can work all the way down to one-on-one relationships. A married couple often finds ways that each member of the partnership can most efficiently contribute to running a household.

But I think there is a conceptual distance between knowing you're not as good at something as a person with whom you have a good relationship and thinking you can't approach the knowledge that the other person possesses. my husband does almost all the cooking in our house, largely because he enjoys it and I do not. But sometimes I need to cook, so it pays for me to learn some of what he does in his cooking for those unforeseen times when I need to cook a family meal.
