I have a friend to whom I'm quite close.
She's a SAHM with two girls and her husband is a joiner who works all the hours under the sun to allow her to stay at home with the kids. She readily admits this and is grateful to him for working so much.
The issue is that her house is an absolute tip. She always says that she can't stay in the house because she thinks her DDs would be bored or resent being in the house 
Her husband has pleaded with her to do a little around the house because he's left to do washings and tidy the house after longs shifts at work. She has asked my opinion on it a couple of times. Specifically if her house was a mess and if her husband is being unreasonable to expect her to do some basic housekeeping while he's at work.
I really didn't know what to say. Obviously I mind my own business but I was actually asked straight out. I wanted to say yes your house is a disaster and yes you should do some tidying and stay in for a day or so a week to do this as your DH is knackered!
What would you say? I've kind of changed the subject but no doubt it will come up again!
