The pressure to clean

My husband's company pays employees and their spouses $100 each to simply go through a 30 min health screening once a year. My appointment is tomorrow morning. The problem? Hubby will be busy helping my dad move, meaning my mother-in-law will be coming over to watch the girls. This means I will be up half the night cleaning my house just so she can come over for an hour. Don't get me wrong, my house isn't a complete sty, but it's hardly spotless either. One of the main issues is the perpetual pile of dishes in the sink. Yes, part of it is the fact that I have three, sometimes four, young children living here, but let's face it, there is also a little laziness thrown in there. I simply hate cleaning. So why am I worried about doing it tonight? The mother-in-law factor. She's one of those people who's idea of dressing up is putting on a T-shirt that doesn't contain foul language. She's one of those women who mows lawns and seems to enjoy vacuuming and stripping wall-paper. She doesn't understand just wanting to relax for a little while when you get the chance. She doesn't say any thing, but you just KNOW she's judging you. My husband's also not afraid to let me know that his mom always had their house spotless, even when he and his sisters were little. So, whenever she babysits, I spend hours cleaning...maybe this is why hubby and I only go out a couple times a year! The irony is, as spotless as the rest of her house is, she has ferret crap all over the place...literally. She lets them run loose in her house and has "poopy pads" laid down in every room. Yes, at any given moment, there are visible piles of crap in every room of her house. Maybe I shouldn't agonize about the cleaning quite so much....
