you can say so, without hurting anyones feeling. The days that you don't want to you can always say that you are busy and you have errands to run and won't have to be bothered until you feel like it. Even though it's been stated several times now, it deserves reiterating: You need to tell them they're not welcome at your house everyday! You don't have to be rude about it, just politely state that you can't entertain their company on a daily basis. If you're just too uncomfortable to broach the subject directly, take the advice about giving them housework to do. Either they'll get the hint and stop coming by everyday or you'll have free maid service from now on!!
