Another thing, Mrs. Davis should charge Walter for those huge breakfasts he gobbles up each morning. I am sure when Mrs. Davis goes to the supermarket she does not just walk out with eggs, bacon and ham without having to pay for them.
Why dont you pay that woman what you owe her, even if you have to get a loan from the bank. She has been more than nice to you. More than patient. If you cannot pay her every month to stay with her THEN MOVE!!
