Let's say you shared a class with someone and she smelled like urine, what's the best way to let her know without embarrassing her? I was in the class room the other day and this girl comes up close to me to examine something on the table and as she passes me, the most horrible stench enters my nostrils. Definitely sure I'm not the only one who smelled it, smelled her... because the air was absolutely pungent.

I really want to tell this girl, but it's very awkward. Suggestions? Ideas? Perhaps I should leave a note on her car windshield?
