Mommy! My uncle is here!

So my daughter and I were waiting in line to check out and JCPenny last Saturday, and she said something that quite surprised me.
"Mommy! My uncle is here!"
I tried to explain that, no, he wasn't.
"Yes he is Mommy!" She insisted, while shaking her butt and throwing her hand on her tiny hip.
I looked around nervously, because she was being quite loud. Again, I tried to gently state that her uncle, was not indeed in the store.
"Yes he IS Mommy! I smell him!"
I nearly fell on the floor.
Nearby was a woman who was obviously a smoker.

The kids don't know about their uncle's habit. He had visited our house the night before and as always, he needed to step outside to "make a few cell phone calls" during his visit.

Why do I think it won't be a secret for long
