Sounds like she is over reacting. Was the necklase expensive? Was it really special to her? Those could be some reasons she is upset. I would keep looking for it and if you can't find it maybe find a way to replace it.
yea i am replacing it. i already told her that and shes still over reacting. its lost..im replacing it..wot more can i do/say. she need 2 calm the fuck down
so next time her mom calls you, tell her that she was the one who let u borrow it w/o even asking to and u tried giving it back but she said to keep it
but do try looking for it.
Hmm, is there any way she could have moved it to get you in trouble?
