How long can u stand your house floor not cleaned?

1 day, 2 days, 3 days or 1 week? My papa can dun mop the floor for not 1 week, not 2 weeks but 3 weeks!!!! If mummy didnt ask him to mop he can dun mop the floor for years! What's the reason? Bcos papa said he didnt opened the windows. So if he didnt go out for 1 month, he no need to bath for 1 month also??? Yucks.......
