I like a clean house. When I was home full-time I fought messes like a housefire all day. Now that I work full-time and hubby is home with the kids...mess doesn't begin to describe it! So, my version of clean has changed. As long as the dishes are washed and the trash cans are emptied...and the laundry is pretty much caught up, I'm happy. I have my boys pick up their stuff just before bedtime so I don't get overwhelmed with the clutter first thing in the morning.
I just think you should do what you can and until company is coming, don't worry about it! It's not going anywhere, that's for sure! Time with family is more precious than how "neat" the environment is.
