Hand her copy of the reciepts for the cost of restoration and tell her , you gave it to me with no strings attached as to your getting it back , your asking for it back now that its fixed isnt fair so what I want from you is for you to pay for the repairs or the chair stays where it is. if she wont agree to pay the cost then I guess it stays put. will she be happy , no , will she see the error of giving it with no strings , who knows.
