Well I am very happy that things are working out right for you in this. I just read this post this morning and was glad that I hadn't seen it until after you spoke to your landlord.

As for your SIL? I think a good verbal slap upside the head is in order. Tell her that perhaps she should volunteer at a shelter somewhere since she seems to have to much time on her hands. That way she would be doing something positive with her excess energy rather than wasting it butting in on someone else's life whom she has no business being in.
