When my father died, my mother decided to move back to her hometown but my sister, who's 20 and still was living with our parents, didn't like the idea. My mother then asked me if she could stay with me because she wanted to sell the house and leave as soon as possible and my sister would need some time to get organized and go on her own. I guess my sister wasn't planning on leaving because she made it really hard for me to tell her to leave, at least for now...
