Sadly, she took the chip out... no tracking her with that
Would be handy to have something like that on her though, she often forgets to call when she's coming home from her evening shift, making timing of dinner a bit difficult.
Y'know, there's a drug used as a sedative in large animals that is fatal to humans - represses the part of the brain that controls breathing. It has an antidote, though, and anyone that chooses to use it knows that you prepare a dose of the antidote first, so if you accidentally inject yourself with the sedative, you hopefully won't die.
