Olivia: (really excited voice)  Oh my gosh Mom!  You're wearing your cancer purse.

I switched to the purse cover to the one that some of the proceeds go to the Huntsman Cancer Foundation.

Mom:  Yes, I did. 

Olivia: (even more excited voice) Oh Mom, do you have cancer (like she's asking me if I have ice cream)?

Clearly she has no idea what cancer is yet . . . and thank goodness for that.
