I think she left it on the roof of her car when she was getting in and forgot to pick it up when she got in. You see people do the same thing in commercials with stacks of paper or coffee mugs
I work tech support for a cellphone company. I've actually had someone run over their phone and ask if it was still covered by warranty. Also, a lot of people assume putting it in rice will magically deactivate the liquid detector after dropping it in the pool/river/ocean/lake. It really doesn't.
Did she leave it on the hood?
