I'm barely up off the couch for a few minutes before I feel out of breath and exhausted from just STANDING there, ahhh! I need to vacuum, mop the floor, take a shower, and get the kids ready, etc etc, because we're having some family over for Christmas in less than two hours. How am I going to do this?? Thank goodness A) my dh has been helping pick up all day, went to the store, and is cooking the meal, and

I don't feel like this all the time yet.
Re: Whew, it's one of those days...
Oh boy do I know what you mean. I get so exhausted just showering some days!
I say you skip the mopping. Your in-laws will never even notice, and you'll save yourself an aching back all evening! In fact, now that I think about it, light a bunch of candles instead of over-head lighting and you won't have to vacuum either. :-D
Good luck! Can you put some swiffer cloths on the floor and have the kids push them around the floor with their feet? That would be as close to mopping as I would get.
