sorry, I didn't mean to offend. My basic thought was this seems like a big case of "telephone". you say your son doesn't really communicate with the girl so this could very well be "ramped" up. Your son heard this from another student who sounds like they are not found of your son so it's not beyond the realm of possibility that she played the "my mom is a doctor" to give credance to her gossip. My concern is of course accusing some one of some thing that can have very very serious implications on the basis of "he said, she said" especially in a high school setting. You call the hospital admin without proof and it turns out to be not true, it's still a very big deal ESPECIALLY for a doctor.
