My SIL called my husband last week saying that their mother was going to give her money to drive to Phoenix to live with us until she found a job.

What? And who invited her? My husband asked if she had any interviews. Of course not. He also asked if she had worked out with her baby daddy that it was okay to take her son to Phoenix with her. She planned to just take him since she wants to break up with him! Double WHAT?! Anyway, my husband emphatically told her that we do not have a guest room and would not welcome her to kidnap her child and hide him in our home away from his father. He also told her that he would appreciate if their mother would stop hatching hairbrained plans involving us supporting his sister and her baby. BTW, she has a college degree but won't keep a job. Yippee! I prefer when I'm not communicating with my inlaws.
