The work is more difficult then doing a desk-job X2 give them that! Dealing with clients and boss is alright they're not family! A stay home mom has to please the husband, the kids, the inlaws and make sure ALL of them are happy and satisfied at the same time too!
Yes, the man of the house provides for the family.. the lady draws-up the grocery list, and shops for it.. plans menu's way in advance and keeps everyone's taste in mind. The lady keeps up with all school activities, and medical issues the kids might have.. the day to day running of the house which may just seem like an hour or two's work.. but it is infact an entire days work. It's physical and mental work both.. with huge doses of stress if MIL is visiting!
