what do you think happened? do you really think that someone broke into your home, with no signs of forced entry, just to fuck with you? who would do that? who could do that? you've suggested that someone may have been snooping to steal your ideas, but if someone was really a thief, and they knew enough about the dolls to use them to fuck with you, why in the hell wouldn't they have stolen them?
As my other posts said, I think that someone came in while I was gone but now I have taken steps to suprise anyone who enters my home without my permission to see to it they won't ever be able to that again.
