Mil wants to bring her mother (is it GMil?) and said to dh that we can go for a walk with DC while GMil stays at the house while watching a film because she can't walk far. I don't want to either have to look after her or to leave her alone in my house because I barely know her and she can barely walk and is becoming forgetful. I don't like the idea of leaving someone I barely know in a room or house alone for what could be a few hours. I have no idea if she is trustworthy or that she wont look in rooms, cupboards or drawers. According to mil she is a narcissist which I have no evidence for or against because I barely know her.
