What if the girl didn't know what a vibrator is (bc that's the toy we're talking about) and had decided to Google it to find out? How can the dad know she was trying to PURCHASE one? Maybe she heard a new word from her friends or the TV and looked it up, found an Amazon page filled with pictures of what she was looking for and got grounded for a month for getting caught. Something similar happened to me (though my punishment wasn't as severe) and all it taught me was not to research new words I heard. Took me a while to learn that a sextant actually has nothing to do with sex.
