Perfume and Chin Rests

I was tuning the violin of an 11-yr-old.  When I gave it back, she sniffed the chin rest.

Me: [raised eyebrows]
Girl: Just checking...
Me: Mmm?
Girl: Sometimes, when Ms T tunes my violin... well, she wears perfume and it's really strong and you can smell it on the chin rest.  Yours though - it's much nicer, not nearly as strong.
Me: Oh... good... It could be worse though [thinking of past teachers who were smokers, or with old coffee oozing from their pores]
Girl: Yeah, it could be cologne.  Yerk.
