I've got a lot of things in my house, spirits, shinigami, etc. I'm obviously going to ask them to come with me, those that are linked or otherwise. If they're linked, I can free them. My policy is that they can stay here as long as they want if they don't bother me, don't hurt anyone(obviously), and take fighting or arguments elsewhere. So really the same as humans...Anyways, my friend is funny. I never tell them to leave her alone, and actually sometimes ask them to bother her, so she wakes up from something touxhing her or moving. Well, they've got to have fun too, right? One time, when she was sleeping with her butt in the air and Ididn't feel like getting up to kick it, one of them did it for me. Also, everyone who comes over here seems to have this happen to them once. The battery on whatever electronic device they have with them will suddenly show as low, then later, it's still full.
