Should husbands and wives have different roles within the family? Why / 
why not?
A.
 
A husband and a wife should play different roles for different reasons. From 
time immemorial, males are considered as the bread earners while the females 
are the homemakers. But the ideas have changed massively in the current 
days. Now, both the husband and wives are seen engaged in money-earning 
activities. Moreover, they are sharing their responsibilities between them and 
thus they are playing different roles in the family.
