Rolling Stones Bracelet : Good luck charm for Honors Geometry

As I watched Julia do her Honors  Geometry Homework, I was breaking into a sweat just watching! Math and I broke up a long time ago so it's really awkward when we get together.  Ha! 

Then I noticed her Rollingstones Bracelet.  I've heard of the band and have seen the logo for many years . I'm sure I've heard their music yet to tell you what they sing , I haven't a clue! 

I shamed Julia by not knowing if Rolling Stones was one word or two.  This is the look I received. 

Guess I won't be getting the cool Mom award anytime soon!
