Well. Iskierka would never return anything of mine, of course, especially if she could eat it. But why would you have recieved a gift that was not meant for us? It makes the most sense that it should have been meant for us, and if you keep insisting it must belong to someone else then someone else will insist that it must belong to them, with no way to prove otherwise, and that will be difficult indeed to sort out. It seems to me it would be much easier to just accept it.
