I think it would also be a good thing if they can keep from panicking under a sudden surprise so they don't clamp down hard with their teeth. That might get messy. :dunno::1orglaugh
Being able to stand on her head, whilst shaving her armpits and blowdrying her hair all at the same time she's blowing me. If she cant do all of that its not worth it.
I read in a book, that I borrowed from a friend a few years ago, that supposedly happened at least once. The guy came in with bite marks and the woman with puncture wounds to the scalp from a fork. She had sneaked under the table are a restaurant to surprise her hubby after dinner. she had a seizure and he panicked and stabbed her with a fork. If I remember right it was something like Strange but True Stories from the ER. Not sure if I would believe it but I wouldn't be surprised by it.
