This is for GIRLS!

This afternoon,I went to the bathroom and realized that I left my special purchase on the floor in the kitchen. I asked SBB, "Can you go to the kitchen and get me the grocery bag with the package in it, not the one with the paper towels, please?"
He comes back, not with the bag, but with the package. He says, "This is for YOU, Mommy."
I say, "Thank you, that's exactly what I wanted!"
I'm thinking to myself, how did he know and he continues, "This is for GIRLS! It's for you, Mommy."
Now all along, I was thinking that I am being pretty private, trying to hide my personal business and all.
But I guess not.
