I am on the "re-direct" side. Send her off to do other things that would make life easier for you. I doubt your friend would ever change unless you prove to her that she is going to kill someone with her lack of skills. I personally like a clean kitchen and bathroom. The other rooms can become dusty etc. but not those two rooms. I bleach my dishes and stainless steel every couple of months and keep the stove top spotless. When I visit my two friends with glasstop stove, I freak out just looking at them. I would never say anything to them, because I know I am the one being silly about it. Oh, I am also a clean refrigerator freak too!

Just send that lady friend of yours to the yard to prune, or the store to shop, or the vacuum to clean..... Ask her nicely - no need to upset the living arrangements at this point. Now if she was there forever, I would say that you should address the problem up front - but not just for a couple of months.

Women like their own kitchens - and hands off to everyone else. I have a friend with the most beat up cookie sheets and I would love to give her new ones but she wouldn't use them..... I like new, clean ones.....but that is me....

Enjoy your friend for the time you have together. She will enjoy being there too, if you let her know what makes you happy...without insulting her already established standards, however low they might be....

Good luck. True friends are hard to come by.... and they may not be perfect!
