Soory hun, but I woulda wrote a termination notice when she starting damaging my property..Potty issues aside that is a HUGE NO NO HERE I would also be issuing a bill to her parents for said damage. I also do not tolerate ANY PHYSICAL ABUSE from my dck eithier.

Do her parents know about this?

even if they do that would be my course of action. No ifs ands or buts about it.
