Um... I recalled to my house to find a bag I did not lock down on my steps full of stuff I didn't put there. This is a new house. There is one friend (someone I trust, who would do this, if she could) but no co-owners. I just checked. I have one account, and only my husband knows how to access it (but he wouldn't... he couldn't care less.) It's full of house deco stuff. How in the world did it get there? I know for a fact it wasn't me, and my account is secure. What permissions does a house friend have? Can they lock down bags? I'm not really concerned, but curious more than anything.
