Sister Confusion

After school several days ago Camille showed me a band aid covering a mosquito bite on her leg. This is the conversation that followed:

Camille: "Do you know who gave this to me?"
Me: "No, who?"
Camille: "Olivia's sister"

Hmmm...I was trying to think of who that might be. I must have had a confused look on my face while I thought.

Me: "you mean a teacher gave it to you?"
Camille: "yes"

Still thinking...are there any families at our small Catholic school that have a student with a big sister that teaches??

Camille: "you know, she always wears the brown dress..."
Me: "Ahhh - you mean Sister Olivia" - the nun that teaches kindergarten classes!
Camille: "Yes!"

We've talked about nuns before, but apparently not what they are called :) Now she knows!
