I find it ironic that you think your nephew needs your moral guidance when you currently have another thread wondering if it would be “silly” for your friend to actually pay $159 for a comforter a teen cashier didn’t charge her for or if it’s okay for her to keep it because it was the store’s error. I don’t really understand why you think that’s a “morally ambiguous” question, but when you talk to your nephew I’d try to keep in mind that we’re all fallible. College is a place where students are exposed to new ideas and beliefs. I’d just tell him to be open to it and to learn as much as he can.
