Re: Urgent. Should I get her a lip balm?
Is this an ongoing thing? If so then you may not want to call her on it in front of her friends. She may get defensive. But I've gotten away with some crazy shit as long as I disguise it within humor. Then just say that they're being sensitive if they freak out and I change the subject.
If you want to go the covert way then get some lip balm and you use it first, then pass it to her. If she asks why are you offering just say "I want them primed up for later" followed with a sly smile.
