Is it really that hard to be a housewife?

O.K. I have never ever complained to her that she isn't doing enough! I do 80% of the cooking and clean up after myself everytime. i regularly do the school run and cleaning the outside of the windows and decorating will ALWAYS be my job! lol ! Don't get me wrong i'm not saying it isn't a demanding role.And i understand that she can't "clock off" What i am saying is why does my wife complain about how little i do and how hard she has it? "The washing basket is full again,i've got ironing up to my ears,dishes need sorting AGAIN (from the machine)and i haven't hoovered for 3 whole days,"shock horror!! it goes on and on and on! I really do appreciate what she does for me and my 2 young boys she runs a tight ship and we do our upmost to help keep things clean and tidy (no really we do!) I took a nights regular job to support us without her having to work her 2 days a week and stay at home to enjoy being a mother and we both think its really important for both my sons that their mother brings them up but all i hear is complaints about how its easy for me because i just have to "go to work" and its starting to wear a little thin with me! last time i looked she isn't hand scrubbing and beating our clothes over rocks in the river? you fill up a machine add detergent,softner and push a button, i don't hear the machine complaining? i've pushed a few vacuum cleaners around in my time push the button again and it takes me 20mins top to bottom. Surface polishing a minimalistic house isn't really difficult isn't it (we don't have brass to buff LOL)?! Contrary to popular belief i DON'T just GO to work,for 7.5 hours i have to be PRODUCTIVE.7.5 hours worth of work every day at home i'm sure would make it a palace ! . . . .SO. . . . . why am i being told when i get up from my nightshift that i have to sort that mess out under the stairs,go get groceries and "help out" with the cleaning and iron my own clothes because she hasn't GOT ENOUGH TIME in her busy day!!?? Is it too much to ask that when i do have time off on the weekend and not working overtime that i can be a DAD and a HUSBAND and spend some quality family time ? Or am i asking too much? Is it really that hard to manage your time being a housewife with all these electronic timesaving appliances??
